Lorico [155]

Answer:

0.8

Explanation:

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively

Let's use GG to represent allele 1

Let's use gg to represent allele 2

So we can equally say that;

GG = p = 0.7

gg = q  = 0.3   ( from Hardy-Weinberg Equilibrium)

So, given that the selection coefficient = 0.2

We known that the cross between GG and gg will definitely results to (GG,Gg and gg)

Then the fitness of these genes can be represented as:

1 - s, 1 and 1 - t respectively.

Thus. the allele 1's genotype fitness can be determined as

= 1 - s    ( where s is the selection coefficient)

= 1 - 0.2

= 0.8
