A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessivefor the tr
ait). For the following questions, assume that the population fits the parameters of the Hardy-Weinberg law. What is the frequency of the recessive allele?
Hardy Weinberg law is represented by the equation below
p² + 2pq + q² and states that the frequency of alleles and genotypes will remain constant in the absence of evolutionary disturbances such mutation, natural selection, migration and the population is large and mating is random.
where p² represent the frequency of homozygous dominant geotypes and 2pq represent the frequency of heterozygous genotypes and q² represent the frequency of the homozygous genotypes
p is the frequency of the dominant alleles and q is the frequency of the recessive alleles.
