According to Hardy-Weinberg’s principle, the allele frequency of a population remains constant. How do you interpret the change of frequency of alleles in a population?

As a seasoned tutor registered on UrbanPro.com, let's explore the principles of Hardy-Weinberg and delve into the interpretation of changes in allele frequency, a vital topic in Class 12 Tuition for biology students.

Understanding Hardy-Weinberg's Principle:

1. Stability of Allele Frequencies:

   • Hardy-Weinberg's principle asserts that under certain conditions, the allele frequencies in a population remain constant from generation to generation.
   • The equilibrium assumes an absence of evolutionary influences such as mutation, migration, genetic drift, and natural selection.

2. Equation Reminder:

   • The Hardy-Weinberg equation, p² + 2pq + q² = 1, reflects the equilibrium between genotype frequencies in a population.

Interpreting Changes in Allele Frequency:

1. Genetic Drift Impact:

   • Changes in allele frequency can occur due to genetic drift, especially in small populations.
   • Genetic drift leads to random fluctuations in allele frequencies over generations, deviating from the equilibrium predicted by Hardy-Weinberg.

2. Migration and Gene Flow:

   • Migration introduces new alleles to a population or removes existing ones, impacting allele frequencies.
   • Gene flow between populations can lead to changes in allele frequencies, disrupting the equilibrium.

3. Mutation and Natural Selection:

   • Mutations introduce new alleles, and natural selection acts on existing alleles, influencing their frequencies.
   • These evolutionary forces can drive changes in allele frequencies, deviating from the Hardy-Weinberg equilibrium.
