# Evolution

## Formula

p + q = 1

p^{2} + 2pq + q^{2} = 1

Where :

p = frequency of allele 'A';

q = frequency of allele 'a';

p^{2} = AA genotype frequency;

2pq = Aa genotype frequency;

and q^{2} = aa genotype frequency.

p + q = 1

p^{2} + 2pq + q^{2} = 1

Where :

p = frequency of allele 'A';

q = frequency of allele 'a';

p^{2} = AA genotype frequency;

2pq = Aa genotype frequency;

and q^{2} = aa genotype frequency.
