Question

How do you find the frequency of a recessive allele?

Answer 1

Frequency of a recessive allele:

1. A recessive allele is a form of genetic coding that does not produce a phenotype in the presence of a dominant allele.
2. To compute the frequency of recessive alleles, use the Hardy-Weinberg equilibrium equation.
3. The recessive allele's frequency is denoted by q, and it can be computed by taking the square root of q².
4. The frequency of homozygotes for the recessive allele, which shows a recessive phenotype and can be easily quantified in a population, is denoted by q².

Hardy-Weinberg equilibrium equation:

where,

p² = dominant homozygous frequency

2pq = heterozygous frequency

q² = recessive homozygous frequency
