how does cell division takes place in sexual reproduction?
The creation of two new cells from one involves copying of the DNA as well as of the cellular apparatus. The sexual mode of reproduction involves a process of combining DNA from two different individuals during reproduction. Many multi-cellular organisms have special lineages of cells in specialised organs which have only half the number of chromosomes and half the amount of DNA as compared to the non-reproductive body cells. Thus, when these germ-cells from two individuals combine during sexual reproduction to form a new individual, it results in re-establishment of the number of chromosomes and the DNA content in the new generation.
- Meiosis I can be broken down into four substages: Prophase I, Metaphase I, Anaphase I and Telophase I
- Meiosis II can be broken down into four substages: Prophase II, Metaphase II, Anaphase II and Telophase II
