Question

Given below are two statements:

Statement I: When many alleles of a single gene govern a character, it is called polygenic inheritance.
Statement II: In polygenic inheritance, the effect of each allele is additive.

In the light of the above statements, choose the correct answer from the options given below:

Accepted Answer

:
- Statement I is False: Polygenic inheritance refers to traits that are controlled by three or more genes (e.g., human skin colour), not multiple alleles of a single gene . The condition where more than two alleles govern a character is called multiple alleles (e.g., ABO blood grouping) .
- Statement II is True: In polygenic inheritance, the phenotype reflects the contribution of each allele, meaning the effect of each allele is additive .
