Consider the Color locus. At this locus there are two alleles - red and green. The red allele is dominant to the green allele. I

f the selection coefficient against the green/green homozygote is 0.30, what it the fitness of the green/green homozygote?

Answer:

0.7

Explanation:

Using Hardy-Weinberg equation of genetic variation being constant when disturbing factors such has mutation and others are removed.

p² + pq + q² = 1 and p + q = 1

where p² is the frequency of the homozygous dominant genotype (RR) and q² is the frequency of the homozygous recessive genotype (rr) and 2pq is the frequency of heterozygous genotype (Rr). p represent the frequency of "R" and q represent "g". since the coefficient against the green/green homozygote is 0.30 then

the fitness of the green/green homozygote = 1 - 0.3 = 0.7
