If you wanted to calculate the frequencies of the two different alleles for a particular gene in a
population, what data would you have to gather and how would you use it?
What will be an ideal response?
You would have to sample the population to determine the proportion of individuals displaying the
homozygous recessive phenotypes, which would be equivalent to q2. You would take the square root
of that to determine the frequency of the recessive allele q, and then subtract q from 1.0 to obtain the
frequency of the dominant allele, p.
