Pretend that you are a famous scientist who has been awarded to study the duplication of chromosomes in the somatic cells of humans (N = 23) and lizards (N = 36). Using the cell cycle as the basis for your studies, describe the phases of the cycle and select the phase where you observe the duplication of chromosomes (this was the reason for the award). Compare and explain in detail how the chromosome number of the human and lizard changes as they go through the phases of the cell cycle. Remember to develop your answer and explain how the number of chromosomes changes in each phase of the cycle.
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:
