Remember, the chromosome number in a sperm cell or ovum is half the normal number, or haploid. WebOnce cytokinesis is complete there are four granddaughter cells, each with half a set of chromosomes (haploid): in males, these four cells are all sperm cells; in females, one of the cells is an egg cell while the other three are polar bodies (small cells that do not develop into eggs).
