Which of the following techniques is most likely to lead to heteroplasmy?
A)cytoplasmic donation
B)embryo adoption
C)oocyte donation
D)in vitro fertilization

Question

Quizplus · Accepted Answer

Cytoplasmic donation involves the transfer of cytoplasm (which contains mitochondria) from a donor egg to a recipient egg. This can lead to heteroplasmy, which is the presence of different mitochondrial DNA sequences in a single individual, if some mitochondria from the donor egg are not replaced by those of the recipient egg. Embryo adoption, oocyte donation, and in vitro fertilization do not typically involve the transfer of cytoplasm and therefore are less likely to lead to heteroplasmy.
