Ovums (female egg cells), can undergo meiosis improperly leading to incorrect segregation of chromosomes and ultimately an ovum with an abnormal number of chromosomes. This can lead to aneuploidy if the ovum is feritilized. What may be some of the reasons and mechanisms for this improper segregation?
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
