Problem
For the first couple of problems, you will be working with guinea pigs. Their coat color shows an example of complete dominance - black (B) is dominant over brown (b).
I. A heterozygous black male is crossed with a heterozygous black female. What would be the resulting phenotypic ratio in the offspring?
II. A heterozygous black male is crossed with a brown female. (i) What would be the resulting phenotypic ratio in the offspring? (ii) What would be the probability of getting a black offspring?
