Polygenic characteristics are disproportionately affected by natural selection.

rodikova [14]

Answer:

The natural selection on polygenic traits affects selection.

Explanation:

The natural selection process allows changes in frequencies of alleles in a character that is determined by single gene. The polygenic characteristics are disproportionately affected by natural selection as natural selection affect the phenotype distribution.

This occurs in three ways that are disruptive selection, stabilizing and directional selection.

In MendAliens, normal head top is dominant to Bart head top, in which the top of the head is jagged. Suppose a MendAlien homozyg

Dafna1 [17]

Answer:

The genotypes of the two parents: normal head shape (HH) and Bart head shape (hh)

The genotypes in the F1 generation= Hh

The phenotypes present in the F1 generation= All normal head shape

Explanation:

Let's assume that the allele "H" is responsible for the normal head shape while the allele "h" gives Bart head shape. According to the given information, both the parents are homozygous. The genotype of the parent with normal head shape would be "HH" while that of the one with Bart head shape would be "hh". Since the normal head shape is dominant, all the F1 hybrid progeny would exhibit "normal head shape".
