Test your understanding of population genetics with 5 practice questions.

Practice Questions

Question 1

Which of the following describes the change in allele frequencies due to random chance, particularly significant in small populations?

Question 2

In a population at Hardy-Weinberg equilibrium, if the frequency of the homozygous recessive genotype is $0.09$, what is the frequency of the heterozygous genotype?

Question 3

Which form of natural selection occurs when environmental conditions favor individuals at both extremes of the phenotypic range over intermediate phenotypes?

Question 4

A population of birds has two alleles for beak size: large (L, dominant) and small (l, recessive). If the frequency of the large allele (p) is $0.8$, what is the frequency of individuals with the small beak phenotype?

Question 5

Which of the following is a direct consequence of a 'founder effect' in population genetics?
