Question

A child inherits two different mutant alleles for a recessive disease gene from each parent. This condition is known as:

• A. Compound heterozygosity
• B. Homozygosity
• C. Dominant negative mutation
• D. Heteroplasmy

Hint:

Compound heterozygosity refers to inheriting two different mutations in the same gene, often leading to recessive disorders.

Answer 1

The Correct Option is A

Compound heterozygosity occurs when an individual inherits two different mutant alleles for the same gene, one from each parent. This can result in a recessive genetic disorder if both alleles are defective.
