Answer:
The correct answer is Not Available
Explanation:
From the Hardy Weinberg Law of Population and Genetics,
We have
x²+2xy+y²=1 and
x+y=1
where
x = frequency of the dominant allele in the population
y = frequency of the recessive allele in the population
x2 = percentage of homozygous dominant individuals
y2 = percentage of homozygous recessive individuals
2xy = percentage of heterozygous individuals
Given 2xy = 0.56
from here, y=0.28/x, (the frequency of the recessive allele ) can be obtained
we need to find 'x'
recall, x+y=1, x=1-y
substituting this gives us
y=0.28/(1-y), which becomes,
y(1-y)=0.28
y2-y+0.28 (quadratic equation)
Solving this to find 'y' gives two imaginary values of y
There is no imaginary solution among the options and hence No answer.
