Hardy-Weinberg Practice

What term refers to all of the genes in a population?

• Gene pool

• Allele frequency

• Genetic drift

What can you conclude when allele frequencies in a population are changing?

• The population is surviving.

• The population is reproducing.

• The population is decreasing.

In p + q = 1, what does q represent?

• Frequency of the heterozygous genotype

• Frequency of the homozygous recessive genotype

• The frequency of the recessive allele

• The frequency of the dominant allele

A population of 150 individuals has an allele frequency of 0.61 for the dominant allele (B) and a frequency of 0.39 for the recessive allele (b). Use the Hardy-Weinberg equation to determine the frequency of heterozygous individuals (Bb).

• 0.37

• 0.48

• 0.15

• 0.11

If a population has the following genotype frequencies: AA = 0.42, Aa = 0.46, and aa = 0.12, what are the allele frequencies?

• A = 0.35, a = 0.65

• A = 0.42, a = 0.58

• A = 0.65, a = 0.35

• A = 0.88, a = 0.12
