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:
Down syndrome is a genetic disorder caused by an extra chromosome 21 due to a genomic mistake during cell division.
Down syndrome can have an impact on a people's cognitive abilities and physical growth, as well as causing developmental differences and a higher likelihood of certain health issues.
