The Hardy-Weinberg formulas -

This formula allows detecting  frequencies that change from generation thus allowing a simplified method of determining that evolution is occurring.

- wherein

In a population at equilibrium for a locus of two alleles D and d having frequencies p and q respectively, the genotype frequencies are:

DD=p2,

Dd= 2 pq,

dd= q2

and p+q =1

p2+2 pq +q= 1

According to Hardy - Weinberg principle

In a population at equilibrium for a locus of two alleles D and d having frequencies p and q respectively, the genotype frequencies are:

DD=p2,

Dd= 2 pq,

dd= q2

and p+q =1

p2+2 pq +q2 = 1

so,

p2= 36 out of 100 individual

q2= 16 out of 100

q= 0.161/2= 0.4
