Question

A recessive mutation is one which

  1. Is not expressed
  2. Is expressed only when heterozygous
  3. Is expressed only when homozygous
  4. Is eliminated by natural selection

hintHint:

Is expressed only when homozygous

The correct answer is: Is expressed only when homozygous


    In recessive mutation the allele of the mutation causing gene is the same, and both the recessive gene must be present to express the mutation i.e., in homozygous condition.
