Question

Hemophilia is an X-linked trait caused by the allele h. About 1 in 10,000 males (0.0001) has hemophilia. The frequency of the h allele in males is therefore _____________________.

Answer 1

The frequency of the h allele in males is
`0.01`

Step-by-step explanation:

Given ,

Out of 10,000 males , only one male has hemophilia.

This means that the probability of occurrence of hemophilia is

`(1)/(10000) \\= 0.0001`

This also signifies that the probability of occurrence of genotype causing hemophilia is
`0.00001`

As per Hardy Weinberg's equation,

probability of occurrence of a dominant genotype is represented by
`p^(2)`

Here
`p^(2) = 0.0001`

Frequency of allele h will be given by

`√(p^2) \\`

`√(0.0001) \\= 0.01`
