1:2:1 phenotypic and genotypic ratio is found in

A

Complementary genes

B

Blending inheritance

C

multiple alleles

D

pseudoalleles

Text Solution

Verified by Experts

The correct Answer is:
B
Incomplete dominance is also called blending inheritance. It was first seen in Mirabilis jalapa (4' O clock plant). Here, when red flowers are crossed with white flowers variety, the `F_(1)` hybrid is pink and `F_(2)` ratio is 1 red: 2 pink: 1 white
