Concept

Problem: In rabbits, black fur (B) is dominant to brown (b), and spotted coat (S) is dominant to solid coat (s).A. Give the genotypes of the parents if a black, spotted male is crossed with a brown, solid female and all of the offspring are black and spotted.B. Give the genotypes of the parents if some of the offspring were brown and spotted. Show the Punnet square for this cross.C. What is the probability of obtaining three brown, spotted offspring from the cross in part B?

FREE Expert Solution

A. In this cross, having shown both the recessive traits, it is definite that the female is homozygous recessive for both genes and her genotype would be bbss. The male, on the other hand, could only be definite for one allele for each as the individual shows dominant character for both traits. Thus, for now, he could only be assigned as B_S_.
