Question

Hello! Please help me with this genetics question! Thank you! There is no other information given. It is just asking to determine the phenotypes based on the information given to us.

Question 7 (1 point) p(d) - dark-purple p(m) = medium-purple p(1) = light-purple p(vl)= very pale purple. The order of dominance is p(d)>p(m) > p(1) > p(vl). In the purple penguin, an allelic series occurs at the p locus on an autosome. All alleles affect the color of feathers, and their phenotypes are shown above. The order of dominance is also shown. If a p(m)/p(vl) female is crossed to a p(m)/p(l) male, what would the phenotypes of the trans-heterozygotes? dark. O medium dark and light. dark and medium and light. dark and medium. O medium and light and very pale. O medium and light.

Answer 1

A transheterozygote is a diploid organism that is heterozygous at two different loci (genes). The term transheterozygote is used in modern genetics periodicals in two different ways. In the first, the transheterozygote has one mutant and one wild-type allele at each of two different genes. In the second, the transheterozygote carries two different mutated alleles of the same gene. According to given data, the crossing of Female with P(m)/P(vl) crossed to a Male with P(m)/P(l) produces P(m)/P(m), P(m)/P(l), P(m)/P(vl), P(l)/P(vl). Here the phenotypes are based on dominance order P(m)/P(m)>P(m)/P(l)>P(m)/P(vl)>P(l)/P(vl), which is Medium and light and very pale.

Please study the below table for a clear understanding of the phenotypes produced and dominance order usage.

Transheterozygote Test For Female with P(m)/P(vl) crossed to a Male with P(m)/P(l)

	P(m)	P(l)
P(m)	P(m)/P(m)	P(m)/P(l)
P(vl)	P(m)/P(vl)	P(l)/P(vl)
