Answer:
0.8
Explanation:
Allele frequency reveals to us how frequent an allele is within a population.
It is estimated by numbering the amount of times of it occurrences divided by the overall amount of copies of the gene.
Mathematically:
Allele Frequency,
= amount of times the allele occurs
____________________________
overall amount of copies of the gene.
The alleles frequency of a gene within a population is 1.
Let's recall the hardy Weinberg equation
p + q = 1
Where,
p = the frequency of dominant allele
q = the frequency of recessive allele.
Given,
Frequency of dominant allele (green color), p = 0.2
Frequency of recessive allele, q = ?
P + q = 1
0.2 + q = 1
q = 1 - 0.2
q = 0.8
