Chapter 2, Problem 4P
In mice, black coat color is dominant to white coat color. In the pedigree shown here, mice with a black coat are represented by darkened symbols, and those with white coats are shown as open symbols. Using allele symbols B and b, determine the genotypes for each mouse.

Assume that one of the students in your class is homozygous for the “Type A” allele and the other student is homozygous for the “Type B” allele. What blood type(s) would you expect to see in their offspring? What if the second was instead “Type O”? Cross two individuals who both have Type AB blood. What are the expected genotypic and phenotypic ratios in their offspring?
