Solution
Answer a: When cross is done between C/c x c/c there is half chance that progeny will be black.C/c because progeny genotype is independent of other . The chance that all 10 are black is . (1/2)10
B.Answer a: zero; Consider allele for hypo phosphate mia be H and for normal h
When cross is done between
H/Y x. h/ h _---------------------- h/Y. Male + H/ h female
