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%)

A population of 150 individuals has an allele frequency of 0.3 for the dominant allele (B) and a frequency of 0.7 for the recessive allele (b). Use the Hardy-Weinberg equation to determine the frequency of the genotype (bb).

• 0.09

• 0.42

• 0.49

• 0.21

Answer explanation

This question gives you p and q. It is asking you to find the recessive genotype, which is q². Use q (0.7) and square it to find the correct answer.

(0.7)² or 0.7 x 0.7 = 0.49

p + q = 1. If p represents the dominant allele frequency, what would q represent?

• the homozygous dominant genotype frequency

• the recessive allele frequency

• the total amount of alleles in the population

• a measure of fitness in the population

p + q always equals 1. Which answer choice best explains this?

• individual could have a dominant or a recessive allele.

• The population is in Hardy-Weinberg equilibrium. The 1 indicates that the population has not evolved.

• In terms of frequency, 1 is the highest possible number you can have.

• In terms of frequency, 1 is the same as 100%. All alleles in a population added up give you 100% of the alleles.

Which values can be plugged into the equation? p + q = 1

• 0.6 and 0.16

• 0.6 and 0.4

• 0.4 and 0.16

• 0.48 and 0.36

Which of the following is NOT an assumption of Hardy-Weinberg equilibrium?

• Natural selection

• Large populations

• No mutations

• No migration
