it is possible that an alternative mechanism for generating germ cells could have evolved. consider meiosis in a germ cell precursor. if the S shape were skipped, whic meiotic devision would no longer be required
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:

Introduction
When a mother cell divides into two or more daughter cells, this process is known as cell division. Usually, cell division happens as part of a longer cell cycle.
There are two different types of cell division in eukaryotes: a vegetative division (mitosis), in which each daughter cell inherits the genetic makeup of the parent cell, and a reproductive division (gametogenesis), in which the number of chromosomes in the daughter cells is cut in half to produce haploid gametes (meiosis).
