You have sampled an infinitely large, randomly mating Finnish
population in which you know that the percentage of the homozygous
recessive genotype (aa) for lactose intolerance is 36%. Answer the
following:

What is the frequency of the recessive allele? 60%

What is the frequency of the dominant allele? 40%

What are the frequencies of the homozygous dominant and
heterozygous genotypes? 16% and 48%

Nine percent of infants within the Finnish population are born
with severe lactose intolerance (i.e., they are homozygous
