Assertion : Antirrhimum is a good example to understand incomplete dominance. Reason : Heterozygotes show characteristics of both the alleles.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

C. If assertion is true but reason is false

Step-by-step solution

Incomplete dominance is the phenomenon where none of the two contrasting alleles or factors is dominant. The expression of the character in a hybrid or F ₁ individual is intermediate or a fine mixture of the expression of the two factors. The inheritance of flower colour in Antirrhinum is a good example to understand incomplete dominance. There are two types of flower colour in pure state, red and white. When the two types of plants are crossed, the hybrid or plants of F₁ generation have pink flowers. The pink colo
