Question

In a population of 8000 persons, the frequency of dominant allele is 0.6. How many people in this population are showing dominant phenotype ?

Answer 1

0.6 = 6/10 = 3/5

Population of persons = 8000

Frequency of dominant allele = 3/5

People showing dominant phenotype

= 8000×3/5

= 1600 × 3

= 4800

Therefore, 4800 people in this population are showing dominant phenotype.

Hope it helps
