WebHá 1 dia · The morphology of normal and affected individuals' oocytes or zygotes by light microscopy. The normal oocytes extruded PB1 (black arrowhead) and entered MII. Oocytes from individual II-1 of family 1 were arrested at the GV or MI stage. The normal MII oocytes formed pronuclei (white arrowhead) on day 1 after ART. WebA brief interphase separates the two divisions. During this period daughter nuclei and nucleoli appear completely formed, and basal bodies seem to replicate. The second meiotic division ends with the four tetrad products still encased in the zygospore wall; a mitotic division may follow in some zygotes to produce eight cells prior to hatching.

In plants, the zygote may be polyploid if fertilization occurs between meiotically unreduced gametes. In land plants, the zygote is formed within a chamber called the archegonium. In seedless plants, the archegonium is usually flask-shaped, with a long hollow neck through which the sperm cell enters. As the zygote divides and grows, it does so inside the archegonium.
