When working with blood types, we're gonna use the letter I. Both A and B are dominants over O (as O means the absence of A and B) and they also can present codominance between each other (if one allele of each is found, both will be equally expressed). So, as we have the blood types A, B, AB and O, they are represented by:

A - Iᴬ Iᴬ (homozygous) or Iᴬ i (heterozygous)

B - Iᴮ Iᴮ (homozygous) or Iᴮ i (heterozygous)

AB - Iᴬ Iᴮ (codominance)

O - i i (recessive)

Now we must cross a heterozygous A (Iᴬ i) with a O (i i) in a Punnett square, as follows:

As we can see:

- 2/4 (or 50%) of the offspring would possibly be Iᴬ i (heterozygous A blood type)

- 2/4 (or 50%) of the offspring would possibly be i i (O blood type)

Natural selection is a process where the environment changes and populations have genetic variation, leading nature to select organisms with advantageous traits for survival and reproduction.

Explanation:

Complete sentences:

The environment needs to change in order for natural selection to occur because different traits may become advantageous or disadvantageous in different environmental conditions, leading to differential survival and reproduction.

Populations have some genetic variation, meaning that individuals within a population differ in their traits, including physical, behavioral, and physiological characteristics.

Nature selects organisms with specific traits to survive and reproduce based on their ability to adapt to the environmental conditions and compete for resources, leading to the accumulation of advantageous traits over generations.

The way that the processes of artificial and natural selection are different are:  a. In natural selection, the organisms best adapted to survive in the environment are more likely to reproduce and pass on their traits, while in artificial selection, humans choose which organisms survive and reproduce. Option A

Individual organisms with certain phenotypic characteristic values are chosen for breeding through a method called artificial selection. If the chosen characteristic exhibits additive genetic variation, it will respond to selection and change over time.

Because humans (rather than nature) choose which creatures get to reproduce, this process is referred to as artificial selection. The image below demonstrates how farmers have artificially selected for certain traits to develop several crops from wild mustard.

Artificial selection is directed by human preferences and differs from natural selection in that it is not random.
