To get blue owls, you need the functioning enzymes encoded by the A and B genes. The protein encoded by the D gene causes enzyme B to be degraded. a, b, and d are alleles that encode recessive, loss-of-function mutations. Owls that don’t make or don’t deposit the blue pigment are grey. a. In an AaBbdd X AaBbdd cross that produced 48 owls, how many blue ones would you get? b. If the cross is AaBBDd X AaBBDd and produces 160 owls, how many blue owls will you get?
