1. In chickens, black feathers (B)and white feathers (W) show incomplete dominance such that achicken with both the black and white alleles (BW) has grayfeathers. What types of offspring, and in what proportions,would you expect from a mating of a gray rooster and a blackhen?
2. What are the possible genotypes for aman with A blood type?
3. What are the possible genotypes for aman with B blood type?
4. What are the possible genotypes for aman with AB blood type?
5. What are the possible genotypes for aman with O blood type?
6. A child has type O blood and its motherhas type A blood. What are ALL thepossible blood types of the father?
7. A child has type B blood and its motherhas type AB blood. What are ALL the possible blood types of thefather?
8. In Labrador retrievers dogs can haveblack, yellow or chocolate fur. This is due to
a) codominance
b) the interaction of 2 different genes
c) incomplete dominance
