Question

Compare and contrast mitosis, meiosis I, and meiosis II. How many chromatids in a cell at the end of each stage?

Answer 1

Both mitosis and meiosis comes under cell division and is important for cell reproduction. Mitosis is done to increase the number of cells in the body while meiosis is done to produce haploid gametes.

Mitosis does not involve in any change in chromosome number while meiosis reduce chromosome number to half.

Mitosis stages	Number of chromosomes	Number of chromatids
Prophase	46	92
Metaphase	46	92
Anaphase	92	92
Telophase	92	92
End of mitosis	46	46

Meiosis stages	Number of chromosomes	Number of chromatids
Prophase I	46	92
Metaphase I	46	92
Anaphase I	46	92
Telophase I	46	92
In the of meiosis I	23	46

Meiosis II stages	Number of chromosomes	Number of chromatids
Prophase II	23	46
Metaphase II	23	46
Anaphase II	46	46
Telophase II	46	46
In the of meiosis II	23	23
