Question

5. Assume that in the families in Problems "a" and "b" below, the allele for brown eyes is dominant to that of blue. a. A brown eyed man marries a blue eyed woman, and they have eight children, all brown eyed. What are the genotypes of all the individuals in the family? b. A blue eyed man, both of whose parents were brown eyed, marries a brown eyed woman. They have one child who is blue eyed. What are the genotypes of all the individuals mentioned? 6. In guinea pigs, rough coat (R) is dominant over smooth coat (r) and black (B) is dominant over white (b). R and B are independent genes. Cross a homozygous rough black animal with a smooth white one. What are the genotypes and phenotypes of the offspring? Choose any two offspring and cross them, determining the genotypes and phenotypes of the next generation. 7. If a woman who is heterozygous for Type A blood is crossed with a man who has Type O blood. What would be the possible genotypes and phenotypes of their offspring? 8. The roan coat in some cattle is an example of co-dominance. C? represents the red allele and C? represents the white allele. If a roan coated cow is crossed with a red coated bull, what will be the genotypes and phenotypes of the offspring? 9. In poultry, feathered legs (F) are dominant over clean legs (f) and pea comb (P) over single comb (p). If a homozygous feathered, heterozygous pea comb is crossed with a heterozygous feathered, homozygous single comb, what will the resulting genotypes and phenotypes be?
