Hardy-Weinberg Practice

Which Hardy-Weinberg equation represents the genotype frequencies in a population?

• p + q = 1
• p2 + 2pq + q2 = 1
• p2 + pq2 + q2 = 1
• p + 2pq + q3 = 1

Which Hardy-Weinberg factor represents the frequency of heterozygous individuals in a population?

• p2
• 2pq
• q2
• p2 + 2pq

In the Hardy-Weinberg Equation, q² is the frequency of what?

• The recessive allele 
• the dominant allele
• the recessive genotype
• the dominant genotype

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

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.

• Dominant alleles in the population's gene pool will slowly increase in frequency while recessive alleles will decrease.

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