Question

In a population of rabbits, Npp and Nqq are the number of individuals having short and floppy ears respectively, and Npq is the number of heterozygous individuals. Calculate the allelic frequency of p and q respectively in the given population with Npp = 1024, Npq = 64 and Nqq = 512?

• A. 0.66 and 0.34
• B. 0.44 and 0.12
• C. 0.34 and 0.66
• D. 0.8 and 0.2

Answer 1

The correct option is A 0.66 and 0.34

N = Total no. of rabbits in the population 1024 + 512 + 64 = 1600
Allelic frequency (p) $=\frac{2Npp+Npq}{2N}$
$=\frac{(2\times 1024)+64}{2\times 1600}=0.66$
Allelic frequency (p) $=\frac{2Nqq+Npq}{2N}$
$=\frac{(2\times 512)+64}{2\times 1600}=0.34$
