Write two factors affecting Hardy - Weinberg principle.

To remain at Hardy-Weinberg equilibrium, the following criteria should be met. These are: (write any two)

1. A large breeding population.

2. Random mating.

3. No change in allelic frequency due to mutation.

4. No immigration or emigration.

5. No natural selection.

So, the factors that affect the Hardy Weinberg principle includes gene flow, genetic drift, mutation, genetic recombination and natural selection.
