q² (Homozygous Recessive Individual) = .513
q (Recessive Allele) = .72
p (Dominant Allele) = .28
p² (Homozygous Dominant Individual) = .078
2pq (Heterozygous Individual) = .403

Population out of 1000
Homozygous Dominant Individual = 513
Heterozygous Individual = 403
Homozygous Recessive Individual = 78

Steps

1. To find q, find the square root of q²
2. Subtract 1 by q to find p (1 - q)
3. After finding p, square p to find p²
4. Then to find 2pq, multiply 2 by p then q (2*p*q)
5. To make sure your calculations are correct you can use the two formulas                (p + q = 1) and  (p² + 2pq + q² = 1)
6. Finally multiply each value of the individuals (q²,p²,2pq) by the total # of the population (1000) to find the population of each group of individuals
