Q148 / 200 · NEET 2024 (Re-NEET) · Zoology

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
  • Correct answer
    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

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.

Hence, the correct answer is option: 'B'.
