Question

The height of plant is controlled by the 3 genes. The maximum height 24 inches. Minimum height 6 inches. What is the height of AaBBcc?

Answer 1

Answer:

Explanation:

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
