Question

In a plant height is controlled by two polygenes A and B tallest plant is 56 cm and height of shortest plant is 30 cm so what will be the height of plant having genotype AAbb

Answer 1

A polygene is a group of genes that are responsible for a particular type of the trait.

The height of the plant will be 43 cm.

Explanation:

Solution:

(Maximum height - minimum height) / Number of polygene

(56-30) / 2 = 6.5

Now

Combination of two = 6.5 x 2 = 13

As the height of the two plants is given as

                       AAbb = 13 + 30

                                  = 43

Hence the answer is 43 cm.
