Question

Quizplus · Accepted Answer

The fusion of the pronuclei, which creates the zygote, occurs after the oocyte completes meiosis II. During meiosis II, the haploid secondary oocyte divides, producing a second polar body and a haploid ovum. The ovum then undergoes fertilization with the sperm, leading to the fusion of the pronuclei and the formation of a diploid zygote.
