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.

• A. Statement I is true but Statement II is false
• B. Statement I is false but Statement II is true
• C. Both Statement I and Statement II are true
• D. Both Statement I and Statement II are false

Answer 1

Answer: (B)

Statement I is false but Statement II is true

Answer 2

Polygenic inheritance is governed by multiple genes, not multiple alleles of a single gene. In polygenic inheritance, the effects of each allele are additive, contributing to the phenotype. Therefore, Statement I is incorrect, and Statement II is correct.
