Phenotypic and genotypic ratio is simila...

Phenotypic and genotypic ratio is similar in case of

A

complete dominance

B

incomplete dominance

C

over dominance

D

epistasis

Text Solution

Verified by Experts

The correct Answer is:
B
Incomplete dominance is the phenomenon of neither of the two alleles being dominant so that expression in the hybrid is intermediate between the expressions of the two alleles in homozygous state. `F_(2)` phenotypic ratio is `1:2:1`, similar to genotypic ratio.
