Answer:
0.8
Explanation:
Allele frequency simply shows how common an allele is in a population.
It is calculated by counting the number of times it appears divided by the total number of copies of the gene.
The frequency of all alleles of a gene present in a population must equate to 1.
so,<u><em> p+q=1</em></u>
If the Allele frequency of A whose phenotype are green grasshoppers is 0.2 to find the frequency for a (brown grasshoppers) will be';
<u><em> 1-0.2=0.8</em></u>
