With the help of an algebraic equation how did Hardy Weinberg explain that in a given population the frequency of occurrence of alleles of a gene is supposed to remain the same through generations?

Explanation

To explain how Hardy-Weinberg's principle demonstrates that the frequency of alleles in a population remains constant across generations, we can break it down into several steps using an algebraic equation.

### Step-by-Step Solution:

1. **Understanding Alleles and Genotypes**:
- In a population, a gene can have two alleles, which we can denote as **P** and **Q**.
- The possible genotypes formed from these alleles are:
- Homozygous dominant (PP)
