Answer:
0.28
Step-by-step explanation:
Hardy-Weinberg equilibrium states that the frequency of allele and genotype will remain the same from generation to generation in the the absence of evolutionary influences. Such evolutionary disturbance include: mutation, non-random mating, gene flow, natural selection, genetic drift and others ,
His equilibrium is denoted by the equation;
p² + 2pq + q² = 1
p² + 2pq represent the dominant phenotype which comprises of f (DD) = p² and f (Dd) = 2pq and is equal to 0.72
then the f(dd) =q² = 1 - 0.72 = 0.28
