The height of a plant is under the control of polygenic inheritance. The genotype of a plant `A_(1)A_(1)A_(0)A_(0)` has 56 cm and the height of plant `a_(1)a_(1)a_(0)a_(0)` is 26 cm. what is the contribution, of each polygene?

A

30 cm

B

8.5 cm

C

15 cm

D

7.5 cm

Text Solution

Verified by Experts

The correct Answer is:
D
Contribution of each polygene `=(56-26)/(4)=7.5cm`. `A_(1)A_(1)A_(0)a_(0)` has three polygene and, therefore, height will be `26+7.5+7.5+7.5=48.5cm`
