ANSWER:

Penetrance in biological science is that the proportion of people carrying a selected variant of a cistron that additionally categorical an associated attribute The penetrance is 100%. Common examples accustomed show degrees of penetrance ar typically extremely penetrant.Individuals with constant genotype can even show totally different degrees of constant makeup. Expressivity is that the degree to that attribute expression differs among people. not like penetrance, expressivity describes individual variability, not applied mathematics variability among a population of genotypes.

A researcher is interested in a novel gene in drosophila called “COVID” which causes the flies to become antisocial and maintain a large distance from other flies. She performs two “reciprocal crosses” to determine the possible genetics of this gene. First, she crosses a true-breeding COVID female to a true-breeding wild-type male and produces the following progeny: All of the female progeny are wild-type and all of the male progeny from this cross are COVID. Next, she does a reciprocal...
