In Hardy-Weinberg equation, the frequency of heterozygous individual is represented by

A

`p^(2) `

B

`2pq`

C

`pq`

D

`q^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B

Hardy-Weinberg principle states that the allele frequencies in a population are stable and remain constant from generation to generation This can be expressed by the equation :
`p^(2) + 2pq + q^(2) = 1 `
or `(p +q)^(2) =1`
Where, `p^(2)` represents frequency of homozygous dominant genotype, 2pq represents the frequency of heterozygous genotype and `q^(2)` represents the frequency of homozygous recessive genotype.
Hence, option (b) is correct
