Q:

A polygenic trait is controlled by 3 genes A, B and C. In a cross AaBbCc x AaBbCc, the phenotypic ratio of the offsprings was observed as 1 : 6 : m : 20 : m : 6 : 1. What is the value of m?

A) 10	B) 15
C) 18	D) 24

Answer & Explanation Answer: B) 15

Explanation:

Here crossing is AaBbCc x AaBbCc

As it is trihybrid cross,

we know, Number of zygotes formed = $4^{n}, where n = 3$

$4^{3} = 64$

Given ratio of offsprings = 1 : 6 : m : 20 : m : 6 : 1

Now, 1 + 6 + m + 20 + m + 6 + 1 = 64

34 + 2m = 64

2m = 30

=> m = 15.
