What is the final product of meiosos?
4 nuclei
When cells divide to create 2 identical cells the produce by?
meiosos
What occurs in meiosos but not in mitosis?
lining up of tetrads, crossing over, and separation of homologous chromosomes.
What is the importance of crossing - over during the first division of meiosos?
It increases the likelihood that the resulting cells will contain different genetic combinations.
How many times does the cell divide during meiosos?
Chromosones are divided two times. Once during meiosis I and once during meiosis II.
Eukaryotic cells do not reproduce through binary fission Instead they reproduce through a process called?
Eukaryotic somatic (non-sex) cells reproduce strictly by mitosis. Sex cells use meiosos and mitosis.
What happens if nondisjunction occurs during meiosos?
If nondisjunction occurs during meiosis the result could be a wide range of mutations. Most likely it would result in mosaicism meaning there will be a mixture of affected cells and non affected cells.
How is mitosis and meiosos alike and different?
Mitosis is the process in where cells are made throughout the body. The process is called IPMAT, this stands for Interphase Prophase Metaphase Anaphase Telophase Mitosis makes different cells with different functions for specific body functions except for the sex gametes. Meiosis on the other hand makes the sex gametes and its process is the same except it is repeated twice. It is called IPMATPMAT Interphase Prohase Metaphase Anaphase Telophase Prophase Metaphase Anaphase Telophase Meiosis can only make sex gametes and nothing more.
