Web3 Answers. Meiosis starts with a diploid cell and produces four haploid cells. In animals, the starting diploid cell is usually called a germ cell and the surviving haploid cells become gametes ( sperm and ova ). (In animals, the female mitotic sequence produces only one ovum; the other three haploid cells become "polar bodies".) http://www.waynesword.net/lmexer8.htm

WebAll cells in the body, known as somatic cells, with the exception of those that will develop into gametes, undergo a type of cell division called mitosis. (sperm and egg cells). Somatic cells divide and replicate their DNA through the process of mitosis, resulting in identical copies of the original cell's DNA in each daughter cell. WebMost fungi and algae employ a life-cycle strategy in which the multicellular “body” of the organism is haploid. During sexual reproduction, specialized haploid cells from two individuals join to form a diploid zygote. The zygote immediately undergoes meiosis to form four haploid cells called spores ( Figure 7.2 b ).
