In a herd of deer, 98 out of the 200 deer exhibit a white-hair, recessive phenotype. The domianant allele codes for brown hair. What % of the herd would likely be heterozygous for brown hair?  30%, 42%, or 70%

This problem will explore a concept called epistasis.  Epistasis occurs when one set of alleles can mask the presence of a different set of alleles. In humans, normal pigmentation (A) dominates no pigmentation (albino = aa). Black hair (B) dominates blonde hair (b). An albino person will have white hair even though he or she may also have the alleles for black or blonde hair. An albino male who is homozygous for black hair marries a woman who is heterozygous for normal pigmentation and has blonde hair.  What colors of hair can their children have, and what is the probability for each hair color? Two people with normal pigmentation have one child with dark hair, two children with light hair, and two albino children.  What are the possible genotypes for the parents?  If you are not certain about an individual’s allele, indicate this with a blank ( __ ).

determine if the possible alleles are complete dominate, incomplete dominance, or codominance.

Two individuals, labeled A and B as shown in the following figure, what is the probability of individual A and B shares a same allele, as a result of their descent from a common great grandparent?
