A population of flowers is in Hardy-Weinberg equilibrium with an allele frequency for white flowers (w)of 40%.What percentage of the flowers will have the colored or dominant phenotype?

Question

Quizplus · Accepted Answer

In Hardy-Weinberg equilibrium, the frequency of the dominant phenotype can be calculated using the formula: p^2 + 2pq, where p is the frequency of the dominant allele and q is the frequency of the recessive allele. Given q (frequency of w, the recessive allele) is 40% or 0.4, p (frequency of the dominant allele) is 60% or 0.6. Thus, the frequency of the dominant phenotype = (0.6)^2 + 2(0.6)(0.4) = 0.36 + 0.48 = 0.84 or 84%.
