A population of pea plants has two flower color alleles, red and white. Red is
dominant to white. What is the frequency of red flower alleles in a population of
1,000 pea plants in Hardy-Weinberg equilibrium, if there are 160 pea plants with
= 0.16, so white, q, = 0.4, and red, p, = 0.6.__________________
A small, captive breeding program for rhinos in a zoo has only 8 individuals.
What assumption of Hardy-Weinberg does this population violate?
Infinite population size (inbreeding/random mating also accepted)
For mutant alleles (i.e., those that have amino acid substitutions), natural selection
guarantees that the beneficial alleles and the deleterious (harmful) alleles found in
populations will most often be of what types?
a. Dominant and dominant, respectively.
b. Dominant and recessive, respectively.
c. Recessive and dominant, respectively.
d. Recessive and recessive, respectively.
