The MN blood group is of interest to population geneticists because (a) people with genotype MN cannot receive blood transfusions from either MM or NN people (b) the MM, MN, and NN genotype frequencies can be observed directly and compared with calculated expected frequencies (c) the M allele is dominant to the N allele (d) people with the MN genotype exhibit frequency-dependent selection (e) people with the MN genotype exhibit heterozygote advantage

You are a scientist studying a population of beetles. Beetle color is controlled by two alleles at a single genetic locus. AA beetles are blue, Aa purple, and aa pink. You count 30 blue beetles, 10 purple beetles, and 40 pink beetles. a) What is the frequency of the A allele? [ Select ] b) What is the observed frequency of the Aa genotype? 1 Select ] c) Under Hardy-Weinberg equilibrium, what is the expected frequency of the aa gentoype? [ Select ] d) Is this beetle population evolving? I Select ]
Considering the Hardy-Weinberg theorem’s assumptions, which of the following statements is NOT correct?  (Recall that there are certain assumptions that must be true in order for the Hardy-Weinberg theorem to accurately predict genotype ratios in the next generation.)a) The population must be very large so there random genetic drift will not occur.b) No natural selection can occur.c) Mating must be random.d) Individuals must migrate into and out of the population so that gene flow will occur.e) Mutations must not occur.
