Biology: Gene and Daughter Cells
W4Q1
Meiosis is the process by which cells divide and create living creatures. Without meiosis we cannot have the process of mitosis, which is the process by which cells of tissue are created for living creatures. When meiosis occurs 4 daughter cells are created, while only 2 are created in mitosis. With the creation of 2 daughter cells the new cells will be similar to the parent cell, but will have differences, as there more parent cells involved. When mitosis occurs the daughter cells will be identical to the parent cell, since only 1 cell is involved. Meiosis is needed for sexual reproduction, while mitosis is needed for general growth, repair, and cellular reproduction of the body. The process of mitosis is not involved in any sex cell, and meiosis is not involved in any cell with the exception of sex cells. Since meiosis has more cells involved (parent cells) this process has a few more steps than what mitosis does. There are several similarities between the process of mitosis and meiosis. For example both processes occur at the cellular level. Both processes share genetic material from the parent cell to the daughter cell. In conclusion without meiosis we would not be created and therefore not need the process of meiosis, because cells would not be able to form.

Mendel used mathematics and experimentation to derive major principles that have helped us understand inheritance. His ideas were totally different than the explanation for passage of characteristics from parents to offspring that was common to his time. List and describe his principles and describe how each contributes to genetic variability. How might biology have be different if his discoveries had not been lost for decades? Be prepared to
