can i play too? :wink:

Meiosis is the process by which germ cells with 46 chromosomes develop into sperm or egg cells with 23 chromosomes. There is evidence that testicular germ cell tumors may form when something abnormal happens during meiosis. Instead of forming normal sperm cells with 23 chromosomes, all 46 chromosomes remain. Usually, these chromosomes become unstable and progressively more abnormal in their shape and number (which is often between 69 and 82). Changes to chromosome 12 are particularly common, and scientists are studying DNA from this chromosome to learn more about exactly what goes wrong during meiosis and how this might be prevented or reversed.

Definitely YES, during metaphase II is oocyte blocked from cell division, but when there are some occurence in pathology of kinases, oocyte began division - result is ovarian cancer
