Question

Quizplus · Accepted Answer

In the technique for developing a third-parent baby, mitochondrial DNA from a female donor replaces the mitochondrial DNA from the mother. This prevents certain genetic disorders caused by mutations in the mitochondrial DNA. The nuclear DNA is still passed on from both parents. Option A and D are incorrect as the nuclear DNA is not partly taken from a male or female donor. Option B is incorrect as the fertilized ovum already contains mitochondrial DNA from both parents, and adding more would create a four-parent scenario.
