What is the Hardy-Weinberg equation
p2 + q2 = 1
p2 + 2pq + q2 = 1
2pq = 1
p2 + 2pq + q2 = 100
In the Hardy-Weinberg equation (p2 + 2pq + q2 = 1), what does p represent
a species
a dominant allele frequency
a recessive allele frequency
a neutral allele frequency
In the Hardy-Weinberg equation (p2 + 2pq + q2 = 1), what does 2pq represent
the number of heterozygous individuals
a dominant allele frequency
a recessive allele frequency
the number of homozygous individuals
The percentage of the homozygous recessive genotype (aa) is 36%. Using that 36% and the Hardy-Weinberg equation (p2 + 2pq + q2 = 1), calculate the frequency of the 'a' allele.
