00:01
Which is not true about the daughter cells of mitosis or meiosis.
00:06
A, in mitosis, the daughters are identical.
00:09
B, in mitosis, the daughters are diploid.
00:12
C, in meiosis, they are haploid.
00:15
In meiosis, they are genetically identical.
00:18
So there are two types of cell division here.
00:21
Mitosis and meiosis.
00:23
In both cases, you start out with a diploid parent.
00:27
So diploid means it has pairs of chromosomes.
00:31
Pairs of chromosomes.
00:33
Haploids only gets one from each pair.
00:38
So your liver cells, heart cells, skin cells, neurons, all of these are diploid.
00:43
They each have 23 pairs of chromosomes.
00:47
Only your gametes are haploid.
00:49
So these are the gametes, which are the egg cells and the sperm cells.
00:54
So mitosis is to make other body cells.
01:00
So that's important for growth or for repair.
01:03
And to do that, it is making two identical daughters, two identical diploid daughters.
01:14
So if we follow the fate of a single pair of chromosomes, at some point it is replicated.
01:23
So it now has two copies of the dna in each chromosome...
