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
Detailed Solution
Statement I incorrectly describes multiple alleles (many alleles of a single gene); polygenic inheritance actually refers to a character governed by more than one gene (multiple genes), so Statement I is false. In polygenic inheritance, the contribution of each gene/allele is additive, producing a continuous range of phenotypes, so Statement II is true.
