Question

A population of 1,500 rabbits is made up of 975 white rabbits, the dominant trait. How many of the rabbits are likely to be heterozygous for the trait?

Answer 1

726

Explanation:

Firstly we put the Hardy Weinberg equation at the back of our minds;

p² + 2pq + q² = 1

The 975 represents - p² + 2pq

The remainder 525 (1500 - 975) represents – q²

q² = 525/1500

q² = 0.35

q = √0.35

q = 0.59

Allelic frequencies of a gene add up to 1

p + q = 1

p + 0.59 = 1

p = 1 – 0.59

p = 0.41

TO find the heterozygous individuals we first find their gene frequency;

2pq

2 * 0.41 * 0.59

= 0.4838

= 0.4838 * 1500

= 725.7

= 726
