Question

Height of mango plant is controlled by two pairs of polygenes the maximum height of plant is 42 metre and minimum height is 30 what will be the height of a plant?​

Answer 1

Answer:

Contribution of each polygene = (Maximum height - Minimum height)/No. of polygene = (30 - 10)/6 = 3.3

Contribution of dominant polygene in plant having genotype AaBbCc= 3.3 x 3 = 9.9

Height of plant with genotype AaBbCc = Minimum height + Contribution of dominant polygene = 10 + 9.9 = 19.9 cm
