In F₂ generation, a ratio of 1 : 4 : 6 : 4 : 1 is obtained instead of 9 : 3 : 3 : 1. It indicates
Options
(a) incomplete dominance
(b) qualitative inheritance
(c) quantitative inheritance
(d) all of the above
Correct Answer:
quantitative inheritance
Explanation:
Quantitative inheritance is a type of inheritance controlled by one or more genes in which the dominant alleles have cumulative effect with each dominant allele expressing a part or unit of the trait, the full trait being shown only when all the dominant alleles are present. In quantitative inheritance the number of phenotypes is 3(1:2:1) when one polygene pair, 5(1:4:6:4:1) when two polygene pair and 7(1:6:15:20:15:6:1) when three polygene pairs are involved.
