Assuming that the population was in Hardy-Weinberg equilibrium for the G locus, what percentage of the gray moths that emerged in 1980 was heterozygous? a) 0% b) 25% c) 33% d) 67% e) 100%

Assuming that the population was in Hardy-Weinberg equilibrium for the G locus, what was the frequency of allele G in the gray moths that emerged in 1980? a) 0.33 b) 0.50 c) 0.67 d) 0.75 e) 1.00

A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessive for the trait). What is the frequency of the recessive allele? a) √0.75 b) 0.75 c) √0.50 d) √0.25 e) 0.25

Scientists are studying several populations of finches on neighboring islands in the South Pacific. Previous genetic analysis has shown that a single gene controls tail-feather length in the finch populations and that the allele for long tail feathers (L) is dominant to the allele for short tail feathers (l). On two separate islands, the scientists … Read more

All of the following are examples of prezygotic genetic isolating mechanisms EXCEPT: a) Male fireflies of different species have differing flash patterns. b) Three closely related orchid species flower on different days. c) The progeny of a cross between two different lizard species fail to develop properly. d) One species of snake lives in water … Read more
