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.
Options
- AStatement I is true but Statement II is false
- BStatement I is false but Statement II is true
- CBoth Statement I and Statement II are true
- DBoth Statement I and Statement II are false
Correct answer
B. Statement I is false but Statement II is true
Step-by-step solution
Polygenic inheritance refers to the inheritance of a trait governed by more than one gene.
In a polygenic trait the phenotype reflects the contribution of each allele i.e., the effect of each allele is additive.
Hence, statement I is incorrect and statement II is correct.
