Here we want to compare mitosis and meiosis with respect to the questions here on the left.
00:07
The first thing i want to do with that is to compare these two processes, which you can see that i've drawn on the right side.
00:13
So we're going to start with two identical cells.
00:16
Each of them has two copies of two chromosomes, one copy each from two different parents.
00:22
And the first thing that has to happen for both of these is synthesis, which just means that every chromosome in the cell is going to be copied exactly.
00:32
Now for mitosis, what's going to happen is that during metaphase, every one of these pairs of sister chromatids lines up on the midline so that when the cell divides, every daughter cell, each of the two daughter cells, gets one copy of every chromosome.
00:50
And this results in daughter cells that are identical to the parent cell.
00:55
By contrast, in meiosis during metaphase one of meiosis one, we get what we call homologous pairs lining up on this midline...
