Now for some genetics questions. Use the back of the previous sheet if you need scratch paper. A rooster with gray feathers is mated with a hen of the same phenotype. Pod type and leaf type are inherited independently. Parents of the above genotypes are crossed.
Lets do the chicken problem one more time.
Remember that when the dominant R and dominant P occur together, the chicken has a walnut comb. A homozygous recessive condition at both loci results in a single comb. Using a Punnett square, illustrate a cross between a heterozygous rose comb chicken and a heterozygous pea comb chicken. John and Mary both have type A blood. John's father has type B blood and Mary's mother has type AB blood.
