Question

In a population that is Hardy Weinberg equilibrium, the frequency if a recessive allele for a certain hereditary trait is 0.20. What percentage if individual in the next generation would be expected to show the dominant trait​

Answer 1

Answer:

P square +2pq+q square...

2pq show dominant traits...

P2+ 2pq+q2 =1

Find value of p

Then put value in 2pq..

(p+q) 2 =1

P+q=1

P =0.8

2pq

2×0.8×0.2=0.32
