Answer #1

People that bring the equal genotype do now not always show the corresponding phenotype in an same manner. these manifestations may additionally vary in intensity, from one individual to another, or the phenotype won't be happen in a certain percentage of providers.

Gene penetrance is the percentage of the phenotypic manifestation of a gene in a given population of provider individuals (the equal genotype). Gene expressivity is the degree (intensity) of the phenotypical manifestation of a gene in every character or organization of people that deliver the gene (the same genotype). Gene penetrance and gene expressiveness may be encouraged by way of the surroundings.

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...
