Question

Quizplus · Accepted Answer

The nuclei from the approaching sperm and egg are called pronuclei, which are the haploid nuclei of the gametes before they fuse to form a diploid zygote. Choice A (prenuclei) is not a recognized term, and choice B (mononuclei) refers to a single nucleus, which is not applicable in this context. Choice D (gametocytes) refers to the original germ cells that undergo meiosis to produce gametes, while choice E (gametes) refers to the mature, haploid reproductive cells themselves, not their nuclei.
