Draw a chromosome and a pair of homologs (or homolog pairs, or homologous chromosomes). Label on the chromosome and homologous pair; the centromere and sister chromatids. In each of these drawings explain how many and where are the Watson and Crick double strand DNA molecules. 2.Diagram of the cell cycle (not cell division) for an organism with two chromosomes (n=2, 2n=4). Include; interphase (including the G1, S, G2 phases), mitosis and cell cycle checkpoints. 3.For an organism with 4 chromosomes draw: a. Metaphase of Mitosis, b. Metaphase of meiosis I, Metaphase of meiosis II.

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:

Expert Solution
Step 1
Chromosomes are made up of proteins and DNA molecules. At the time of cell division they divides so that they may be distributed in the daughter cells formed.
