AP Hardy Weinberg

If a population experiences no migration, is very large, has no mutations, has random mating, and there is no selection, which of the following would you predict?

• The population will evolve, but much more slowly than normal.

• The makeup of the population's gene pool will remain virtually the same as long as these conditions hold
  

• The composition of the population's gene pool will change slowly in a predictable manner

• The population probably has an equal frequency of A and a alleles
  

Select ALL of the following that violate the Hardy-Weinberg assumptions and would lead to a change in allele frequencies in a population.

• natural selection

• large population

• no mutations

• nonrandom mating

• no migration

If all 5 Hardy-Weinberg assumptions are true, a population is said to be in genetic equilibrium. This means

• it is evolving

• it is not evolving

Calculate the frequency of the dominant allele in this population of beetles. Make sure to write your answer in percent form with the percent sign and no numbers after the decimal. (example: 24%)

• 0.4

• 0.6
