Biology

The formation of egg cells begins with a germ cell called oogonium (2n) that undergoes mitosis and gives birth to the oocyte I (2n). The oocyte I undergoes meiosis I that however is interrupted at prophase. After puberty during each menstrual cycle an oocyte I finishes the meiosis I and generate one oocyte II (n) and the first polar body (n). With fecundation the oocyte II then undergoes meiosis II and produces the mature egg cell (n) and the second polar body (n).
