Explanation:

Eye color phenotypes demonstrate epistasis and incomplete dominance. These genes are of the greatest importance for eye color.

Generally speaking a phenotype is an inherited characteristic that we perceive. Eye color, hair color, and blood type are all phenotypes. Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount of melanin in the front layers of the iris. Although eye color is generally modeled as a simple Mendelian trait, additional research and observations have indicated that eye color does not follow classical paths of heredity. Eye color phenotypes demonstrate epistasis and incomplete dominance. It is now clear that eye color is a polygenic trait, meaning it is determined by multiple genes. Genes that affect eye color include OCA2 and HERC2. Both are located on the human chromosome.

Answer:

Mendel worked with pea plants showing complete dominance for various characteristics

- E.g. flower color, plants either have purple flowers or white flowers

- A particular genotype produces a recognizable phenotype

Explanation:

Phenotypes can cause by genes, environmental factors, or a combination of both.

Phenotypic variation, then, is the variability in phenotypes that exists in a population. For example, all people come in different shapes and sizes: height, weight, and body shape are phenotypes that vary.

Answer: oceans

Explanation:

Answer:

More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.

According to Hardy-Weinberg, when a population is in equilibrium, it will have the same allelic frequencies generation after generation, meaning that they are stable, they are not evolving.

When any evolutive force is acting on the population, this equilibrium breacks, and allelic and genotypic frequencies change through generations, differing from the expected ones.  

A) Option 7 is the correct answer ⇒ 0.41

B) Option 6 is the correct answer ⇒ 120

C) Option 7 is the correct answer ⇒ 3.84

D) Option 1 is the correct answer ⇒ The class represents a population that is in H-W equilibrium

E) Option 1 is correct. Comparing the value of Chi-square that I calculated with the critical value of Chi-square for  the appropriate degrees of freedom I conclude that P>0.05. Hence, I reject the null hypothesis.

-------------------------------------------

Allelic frequencies in a locus are represented as p and q, referring to the

allelic dominant or recessive forms. The genotypic frequencies after one generation are p² (H0m0zyg0us  dominant), 2pq (H3ter0zygous), q² (H0m0zyg0us recessive). Populations in H-W equilibrium will get the same

allelic frequencies generation after generation.

The sum of the allelic frequencies equals 1, this is p + q = 1.

In the same way, the sum of genotypic frequencies equals 1, this is

p² + 2pq + q² = 1

Being

 p the dominant allelic frequency,

 q the recessive allelic frequency,

 p² the h0m0zyg0us dominant genotypic frequency

 q² the h0m0zyg0us recessive genotypic frequency

 2pq the h3ter0zyg0us genotypic frequency

Situation: Through PCR, we have determined the PER3 genotypes for a class of students as follows:

 H4/H4 = 125 individuals;

 H4/H5 = 85 individuals;

 H5/H5=24 individuals.

⇒ Total number of individuals= 125 + 85 + 24 = 234

⇒ Genotypic frequencies, F(xx):

 F(H4/H4) = 125/234 =0.534

 F(H4/H5) = 85/234 = 0.363

 F(H5/H5) = 24/234 = 0.102

⇒ Allelic frequencies, f(x):

 f(H4) = p = F(H4/H4) + 1/2 F(H4/H5) = 0.534 + 0.363/2 = 0.534 + 0.182 = 0.716

 f(H5) = q = F(H5/H5) + 1/2 F(H4/H5) = 0.102 + 0.363/2 = 0.102 + 0.182 = 0.284

Questions:

A)  According to the theoreticall frame, we know that 2pq is the h3ter0zygous genotypic frequency. So,  

F(H4/H5) = 2pq = 2 x 0.716 x 0.284 = 0.408 ≅ 0.41 ⇒ Option 7 is the correct answer.

-------------------------------------------------------------------------------------------------------------

B)  According to the theoreticall frame, we know that p² is the h0m0zyg0us genotypic frequency. So,

p = 0.716

p² = 0.5126 ≅ 0.513 ⇒ This is the genotypic frequency.

To calculate the number of individuals carrying this genotype, we need to multiply it by the total number of

individuals.

H4/H4 individuals = p² x total number of individuals = 0.513 x 234 = 120

Option 6 is the correct answer.

-----------------------------------------------------------------------------------------------------------

C)  Up to here we know that 2pq = 0.41 and p² = 0.513

Now we need to calculate q ²

q = 0.284, then q² = 0.284² = 0.08

These are the expected frequencies if the population was in H-W equilibrium.

The expected number of individuals with each genotype are:

 H4/H4 = 0.513 x 234 = 120 individuals

 H4/H5 = 0.41 x 234 = 96 individuals

 H5/H5= 0.08 x 234 = 18 individuals

The observed number of individuals with each genotype are:

 H4/H4 = 125 individuals

 H4/H5 = 85 individuals

 H5/H5=24 individuals

X² = ∑ (Observed - Expected)²/Expected)

X² = ((125-120)²/120) + ((85 - 96)²/96) + ((24-18)²/18)

X² = 0.21 + 1.26 + 2 =

X² = 3.47

The clossest option is option 7 = 3.84. The difference might be related to decimals and rounding.

-------------------------------------------------------------------------------------------------------------

D)  The correct answer is  1 ⇒ The whole class represents a population that is in Hardy-Weinberg equilibrium

The null hypothesis always predict that populations are in H-W equilibrium.

-----------------------------------------------------------------------------------------------------------

E)  

 X² = 3.47

 Freedom degrees = n - 1 = 3 - 1 = 2

 Table p value: 7.82

 Significance level, 5% = 0.05

 Table value/Critical value = 5.991

5.991 > 0.347

Meaning that the difference between the observed individuals and the expected individuals is statistically  significant. Not probably to have differe by random chances. There is enough evidence to reject the null

hypothesis.

Option 1 is correct. Comparing the value of Chi-square that I calculated with the critical value of Chi-square for  the appropriate degrees of freedom I conclude that P>0.05. Hence, I reject the null hypothesis.

A + T = G + C  is constant for DNA.

A ratio of ~1.8 is generally accepted as “pure” for DNA; a ratio of ~2.0 is generally accepted as “pure” for RNA. If the ratio is appreciably lower in either case, it may indicate the presence of protein, phenol, or other contaminants that absorb strongly at or near 280 nm.

In 1950, Erwin Chargaff published a paper stating that in the DNA of any given species, the ratio of adenine to thymine is equal, as is the ratio of cytosine to guanine. This is known as Chargaff's ratio and it was a crucial clue that helped solve the structure of DNA.

Answer:

Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.

In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .

Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.

These compounds interact with one another and end in “life”.

So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

Mitochondria evolved from aerobic bacteria while chloroplasts evolved from cyanobacteria.

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. A eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.

Chloroplast evolutionarily derives from a primitive cyanobacteria that was engulfed by non-photosynthetic cells and, progressively, after losing most of its DNA, became the actual chloroplast that retains only a fraction of the original cyanobacterial genes. Chloroplasts of plants and algae are currently believed to originate from a cyanobacterial endosymbiont.

Find the measure of x and y (3x-3) (4y+4) 60 degrees

Explanation:

Answer:

The Earth is approximately 100,000 years old. Charles Darwin thought that the Earth was only around 6,000 years old, and that all evolution had taken place during that timespan. Knowledge that the Earth is approximately 100,000 years old would not be consistent with Darwin's theory. However, fossils indicating extinct organisms, organismal survival being environment dependent, individuals not evolving, and all living species being related to common ancestors are all consistent with Darwin's theory of natural selection.

The development of gender identity proceeds in several steps or phases. Gender awareness, Gender constancy, Gender identity commitment  is the correct sequence from youngest to oldest.

Gender identity and the assigned sex at birth are two distinct concepts. Usually, the sex assigned at birth is determined by the external genital anatomy. The internal sense of being male, female, or a gender along the male-female continuum, however, is known as gender identity. Gender expression is a way that people let other people know their gender. This can be accomplished through dress, hairstyles, and behaviors.

Sexual orientation and gender identity do not develop simultaneously. Whom a person is physically, emotionally, and romantically attracted to is tied to their sexual orientation. Gender-specific actions and expressions include: Particular bathroom habits, like a girl who insists on standing up to urinate, a dislike of donning the birth-sex-designated bathing suit for the child, a fondness for the undergarments that a different sex wear and an intense desire to play with devices that are usually reserved for another sex.

Mangroves are coastal ecosystems that provide habitats, food, and protection for various species, supporting the food web.

The mangrove ecosystem is a unique and highly productive coastal habitat characterized by mangrove trees, which are specially adapted to survive in saline environments. Mangroves are typically found in tropical and subtropical regions along sheltered coastlines, estuaries, and intertidal zones.

Mangroves are vital in sustaining the ecosystem by providing various ecological services. One of their significant contributions is their role in the food web or food chain.

They serve as a critical nursery and feeding ground for a diverse range of marine species. The intricate network of roots, known as prop roots, provides habitat, protection, and feeding opportunities for numerous organisms, such as fish, crustaceans, mollusks, and birds.

The mangrove leaves and detritus that fall into the water serve as a source of organic matter and nutrients, fueling the base of the food web. Decomposers and detritivores break down the organic matter, which is then consumed by various organisms.

Small organisms, like zooplankton and small fish, feed on the decomposers and detritivores, becoming prey for larger predators such as fish, birds, and reptiles.

Furthermore, mangroves act as a buffer against coastal erosion and storm surges, protecting shorelines and adjacent habitats. They also contribute to water filtration, nutrient cycling, and carbon sequestration, and provide a habitat for numerous endangered and migratory species.

In summary, the mangrove ecosystem plays a crucial role in sustaining the food web or food chain by providing habitat, nursery areas, and food sources for a diverse array of organisms. Their presence supports the productivity and biodiversity of coastal ecosystems, making them an essential component of coastal environments worldwide.
