Question: For the fish model organism Medaka (Aplocheilus latipes), genes at 2 loci (B, b and R, r) determine color of the fish. Fish that have the dominant allele at both loci (B_ R_) are brown, fish with a dominant allele at the B locus (B_) are blue, fish with a […]

By some estimates there are only a couple of thousand great white sharks alive in the wild. Assume that in the frequency of LDH alleles in a sample of 200 adult sharks in a population off of Australia is the following: AA 0.40 AB 0.10 AC 0.05 AD 0.05 BC […]

the body temperature of Arabian oryx fluctuates during the day from about 38oC, the normal body temperature, up to 42oC at midday, and then falls back to 38oC at night. Calculate how much water heterothermia saves over the 24 hr period. Normal Tb = 38oC. Max Tb = 42oC during […]

Mutation can affect the genome in many different ways. For now, consider mutations that (1) result in changes of the third codon position, and (2) result in changes of the first codon position. A) Which type of mutation do you feel would be most likely to be influenced by natural […]
