Answer:
Feathers initially evolved in a role associated with sexual selection.
Explanation:
In species where only males had feathers, these feathers can be considered to have evolved into a role associated with sexual selection. This is because in these species, males used their feathers as a sexual attraction for females, in this case, females chose the males that had more attractive feathers to mate and generate new individuals for the species. An example of this can be seen in the peacock, where the tail with lush feathers is only present in males and is intended to sexually attract females.

and yes their offspring could have straight hair if the genotype is dominant or heterozygous
<h3><u>Answer;</u></h3>
white eyes are homozygous recessive
<h3><u>Explanation</u>;</h3>
- <em><u>Thomas Hunt Morgan work with the fruit fly showed that genes are linked in a series on chromosomes and are responsible for identifiable, hereditary traits. </u></em>He was the first to identify that genes are linked to the same chromosome.
- <em><u>According to his hypothesis he stated that genes that are linked are arranged linearly on a chromosome, while those genes with low combination frequencies must be closer together and thus difficult to separate</u></em>.
- When a gene contains two similar alleles that is, either two dominant alleles or two recessive alleles then it is called homozygous dominant and homozygous recessive respectively. White eyes of a fruit fly is an example of homozygous recessive
