Which of the following is the equation that you use for Hardy-Weinberg equilibrium?

In generation 1, the recessive allele has a frequency of 0.6 and in generation 40, the recessive phenotype has a frequency of 0.36. Is the population is Hardy-Weinberg?

• No, the frequency changed from one generation to another.

• Yes, the frequency changed from one generation to another

• No, the frequency remained the same from one generation to another

• Yes, the frequency remained the same from one generation to another

If a population is suffering from genetic drift, which of the Hardy-Weinberg conditions is not being met?

• no gene flow

• random mating

• extremely large population size

• no mutations

Which of these is a condition that must be met for Hardy-Weinberg equilibrium?

• extremely small population size

• no natural selection

• gene flow

• nonrandom mating

Someone steps on some bugs and randomly removes their alleles from the population. This is an example of

• gene flow

• genetic drift

• speciation

• allele frequency
