Expert Answer

Step 1

A gene is the functional unit of inheritance and it contains two alleles. A dominant gene can be expressed in either the homozygous or heterozygous condition. A recessive gene is expressed only in the homozygous condition.

Frequency of alleles in the population can be estimated using Hardy-Weinberg equilibrium.

There are two equations in Hardy-Weinberg equilibrium,

p2+q2+2pq =...
