WebMar 24, 2011 · Meiosis occurs in the primordial germ cells, cells specified for sexual reproduction and separate from the body’s normal somatic cells. In preparation for meiosis, a germ cell goes through interphase, during which the entire cell (including the genetic material contained in the nucleus) undergoes replication. WebThe female gamete is called an ovum or egg cell, while the male gamete is called a sperm cell. During fertilization, the haploid sperm cell fuses with the haploid egg cell to form a diploid zygote, which contains two sets of chromosomes, one from each parent.
