During oogenesis, the reason for arresting an egg at meiosis I is halving the number of chromosomes in a cell, hence making them haploid. When a female hits puberty, more than one or one primary oocyte undergoes meiosis I, creating secondary oocytes every month. This in turn will begin a second meiotic division, however, is arrested for 24 hours. The wait is for a sperm, to meet in the fallopian tube.
Meiosis II is complete if the egg fuses with sperm, and is then termed as ovum developing into zygote. If meiosis I is followed by mitosis without the sperm uniting with it, over the period of time, clones or exact copies of the mother are produced.
