Answer:
0.8 and 0.2
Explanation:
Hardy Weinberg law states that the allele frequency of the population remain stable from one generation to next generation if no natural selection, drift or mutation occurs in the population.
Let p and q be the dominant and recessive frequency of the population respectively.
The dominant phenotype means p² = 0.64
p = 0.8
and we known that p + q = 1, in hardy Weinberg equilibrium.
0.8 + q = 1.
q = 0.2
Thus, the dominant allele is 0.8 and recessive allele is 0.2.
