You want to identify group one and two answers.
00:03
Group one will be the stage of the myiosis.
00:06
The two will be whether the crossover is impossible and possible.
00:11
Let's look at the first one on the left.
00:13
The first figure show you actually anaphaease 2.
00:22
Because you can see that the problems will look partial blue, placer yellow.
00:26
So this is already after the crossover event during myosis 1.
00:32
And this basically shows you.
00:33
Show you the separation of sister chromatids.
00:44
And on the bottom, group two, e, you should fill in, it's impossible to have myosis during the stage.
00:56
The second one, b, you can see that you have three chromosomes, each has two copy, but there's no homologous chromosome present anymore.
01:04
So this basically is a metaphase two.
01:09
It's metaphase because chromosomes line up in the middle.
01:23
And we know it's two, not one, because there's no more homologous chromosome.
01:38
So each one is a unique kind.
01:41
So basically, this is already a haploid cell.
01:45
So that's why we said that this is a metaphase two...
