WebMar 26, 2024 · To do this, the nuclear envelope forms again and creates an indentation down the center of the cell, called a cleavage furrow. The way the cell determines where to draw this furrow remains unclear and the subject of heated debate among scientists who study cytokinesis. WebTo put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs. …

At the conclusion of telophase in mitosis, the two daughter cells will be diploid and genetically identical to the parent cell. At the end of telophase II in meiosis, there will be four haploid daughter cells. WebThe development of multi-cellular organisms begins from this single-celled zygote, which undergoes rapid cell division, called cleavage ( Figure 18.9 a ), to form a hollow ball of cells called a blastula ( Figure 18.9 b ).
