A black haired mouse was crossed to a hairless mouse. Since itlacked hair, it was impossible to tell if its hair was black orbrown. All the F1 progeny had black hair. When these F1 progenywere mated among themselves (to obtain the F2 generation), 96 wereblack, 43 were hairless, and 30 were brown
(a) What is the approximate observed phenotypic ratio of theseoffspring? (1 points)
(b) Explain the pattern of inheritance observed here (what arethe genotypes that correspond to the observed phenotypes). Assumethat the two genes involved are called A and B. (4 points)
(c) What are the actual genotypes of the original parents? (2points)
(d) What are the actual genotypes of the F1 black haired mice?(1 point)
(e) What are the actual genotypes and phenotypes of the F2black, hairless, and brown mice, respectively (list all genotypesand phenotypes)? (5 points)
