Web8 de ago. de 2024 · The human body is made up of trillions of somatic cells with the capacity to divide into identical daughter cells facilitating organismal growth, repair, and response to the changing environment. This process is called “mitosis.” In gamete production, a different form of cell division occurs called “meiosis.” The outcome of meiosis is the creation of … 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.

Webdizygotic twin, also called fraternal twin or nonidentical twin, two siblings who come from separate ova, or eggs, that are released at the same time from an ovary and are fertilized by separate sperm.
