Question
A recessive mutation is one which
- Is not expressed
- Is expressed only when heterozygous
- Is expressed only when homozygous
- Is eliminated by natural selection
Hint:
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.
