Question

The height of plant is under polygenic inheritance the genotype of plant aabbcc has 70cm and the height of plant aabbcc is 40vm what is the contribution of each gene in the height of plant

Answer 1

Contribution of each polygene = (Maximum height - Minimum height)/No. of polygene = (56 - 26)/4 = 7.5 Contribution of dominant polygene in plant having genotype A1A1Aa = 7.5 x 3 = 22.5 Height of plant with genotype A1A1Aa = Minimum height + Contribution of dominant polygene = 26 + 22.5 = 48.5 cm.
