Mitosis and Meisosis - Chromatid Numbers?

Post by swish123 » Mon Jul 19, 2010 10:29 pm

Hey I am new to this forum. Hope this is in the right section.

My question is about the number of chromatids after mitosis and meiosis are completed.

Here is what I think it is:

Mitosis:

46 Chromosomes(2 Chromatids each cell)
|
2 x 46 Chromosomes (1 Chromatid each cell)

Meisosis:

46 Chromosomes( 2 Chromatids each cell)
|
2 x 23 Chromosomes( 2 Chromatids each cell)
|
4 x 23 Chromosomes(1 Chromatid each cell)

I assume the daughter cell will be responsible to create an identical chromatid for each chromosome.
I tried to look this up but I wasn't able to find a source that emphasized the chromatid #'s.

Thanks for any help

seems to be right.. although the chromatid stuff is a bit confusing. it should be 46 chromosomes (=92 chromatids or DNA molecules) and so on. but as i said i think you got it right.
