Question

Describe the Hardy-Weinberg principle.

Hint:

Remember: No evolution occurs if allele frequencies remain constant; formula is key.

Answer 1

The Hardy-Weinberg principle states that allele frequencies in a population remain constant if no evolutionary influences act upon them. The principle provides a mathematical model to study genetic equilibrium under no mutation, selection, or migration influences. The equation used is: \[ p^2 + 2pq + q^2 = 1 \]
