WebMeiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males).

Each cell is diploid containing the same number of chromosomes. Meiosis: Four daughter cells are produced. WebWhen a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes. Gametes are more commonly called sperm in males and eggs in females.

WebTypes of sexual life cycles. Sexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote.
