第2题

When a population is in Hardy–Weinberg equilibrium, what is the significance of two alleles with equal frequencies (p = q = 0.5)?

A、These are the allelic frequencies found in most populations.

B、These allelic frequencies maximize the proportion of homozygotes in the population.

C、These allelic frequencies maximize the proportion of heterozygotes in the population.

D、These allelic frequencies guarantee that neither allele will become fixed in a population.

E、These allelic frequencies minimize the proportion of heterozygotes in the population.

You are studying cannibals in Borneo and collect the following data with the two co-dominant M and N blood type alleles (LM, LN) segregating at the single-gene locus. What are the genotypic and allelic frequencies for this population? Phenotypes M MN N Total # genotypes 287 665 123 1075

A、LM LM = 0.287, LM LN = 0.665, LN LN = 0.123; LM = 0.885, LN = 0.115

B、LM LM = 0.267, LM LN = 0.619, LN LN = 0.114; LM = 0.5, LN = 0.5

C、LM LM = 0.267, LM LN = 0.619, LN LN = 0.114; LM = 0.267, LN = 0.114

D、LM LM = 0.267, LM LN = 0.619, LN LN = 0.114; LM = 0.576, LN = 0.424

E、LM LM = 0.287, LM LN = 0.665, LN LN = 0.123; LM = 0.576, LN = 0.424
