The population was in Hardy-Weinberg equilibrium from generation 1 to 4. Option C). During this time, allelic frequencies remained the same.
What is the Hardy-Weinberg equilibrium?
The Hardy-Weinberg equilibrium is a theory that states that allelic and genotypic frequencies remain the same through generations.
No evolutive forces are acting on these populations. This is, there is no
- Mutation
- Natural selection
- Genetic drift
- Gene flow
- Mating by selected genotype/phenotype
These populations are in equilibrium because they are not evolving.
Assuming a diallelic gene,
⇒ The allelic frequencies in a locus are represented as p and q.
• The frequency of the dominant allele p(X) is p
• The frequency of the recessive allele p(x) is q
⇒ The genotypic frequencies after one generation are
• p² (H0m0zyg0us dominant genotypic frequency),
• 2pq (Heter0zyg0us genotypic frequency),
• q² (H0m0zyg0us recessive genotypic frequency).
The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
According to this information, the proposed population was in Hardy-Weinberg equilibrium from generation 1 to 4. During this time, allelic frequencies remained the same. Only in the fifth generation, there was a shift in allelic frequencies.
Option C) is correct. generations 1–4
