Answer:
Hazel - 1/4 or 25%
Green - 1/2 or 50%
Blue - 1/4 or 25%
Explanation:
First, let us carry out the cross between AaBB and Aabb using a Punnet's square. The result is as below:
AABb - 4/16
AaBb - 8/16
aaBb - 4/16
(See the Punnet's square analysis in the attached image).
<em>AABb genotype has 3 pigments, hence, would be hazel.</em>
<em>AaBb genotype has 2 pigments, hence, would be green.</em>
<em>aaBb has one pigment, hence, would be blue.</em>
Expected progeny:
<em>Hazel - 1/4 or 25%</em>
<em>Green - 1/2 or 50%</em>
<em>Blue - 1/4 or 25%</em>
The study of artificial selection by Darwin helped him to establish his theory of evolution via natural selection. One of the animals Darwin examined in detail was the domestic rock pigeon. In the 1850s breeding of pigeons was an ancient past time, thus, Darwin decided to keep and breed the pigeons by himself.
While studying pigeons, Darwin established scrupulous determinations of their skeletons and wondered at the breeds' distinct colors, behaviors, and proportions. He also observed the patterns of inheritance of various features, and he demonstrated that birds of very distinct breeds can, however, generate fertile offspring. Thus, supporting the theory that they all originated from a single species.
Answer: predator species would be more sensitive by accumulating toxic material already accumulated in individual prey. It would also depend on different levels of pollution in different niches, so that one species would be more exposed.
