00:01
And no response to this question, let's talk about inge.
00:02
And it says, an organism has a deployed number for chromosomes.
00:05
It means the total number of chromosomes for this organism is four.
00:10
Then this is with the heterocycos with a deep at least on the homologous first pair and the e gene on the homologous on per.
00:22
So this is your cell and this is one chromosome and this is another chromosome.
00:31
And the same for this blue chromosome.
00:33
And here you have your four chromosomes.
00:37
You have here the d gene and you have here the e gene.
00:46
Okay? obviously here initially your chromosome was like this.
00:51
Let's suppose that the gene is found here.
00:54
But after dna replication, this happened.
00:59
The dna was replicated, so your d, your dominant d is now also here.
01:04
Okay, so you have here the d and also the same form.
01:09
For the case if i did here and also here and also here.
01:13
So it is, an on this junction, an on this junction occurs during myiosis 2 that affects one of the chromosomes.
01:22
Draw a cell in anaphase 1, the returting cells in farn in anaphase 2, and the resulting amidst in your drawings show the adage on each chromosome, assuming crossing over doesn't occur.
01:31
So this is your starting cell.
01:34
What happens? well, this is prophes practically because you don't have nobles anymore.
01:39
And then you're going to have a metaphasease, in metaphase, your chromosomes are going to align like this in the middle of a cell.
01:48
During metaphase 1 of myosis 1, your chromosomes are going to align like this together.
01:56
Okay? and the second pair is going to align here.
02:00
Basically, the chromosomes are going to align in pairs in the middle of a cell.
02:03
This is metaphase of myosis 1.
02:06
What happens during anaphase? well, during anapace, this chromosome is going to move to this pole.
02:11
Chromotson to this pole is the same for these two chromosomes, okay? so you have the following.
02:19
The spindle is retract is moving to the pulse and is dragging one chromosome here.
02:29
And the same here.
02:35
And the same is happening for the blue chromosome.
02:46
Okay, obviously you have here that is spectator and it is the week of draw here.
02:50
So you have, for example, here, e, and here you have the excessive.
02:56
And maybe you have here the, oh sorry, this is the black chromosome.
03:00
So you have here the d and the d and you have here the recessive d and maybe you have here the recessive e, recessive e, you have here the dominant d, dominant e, i'm sorry, and dominant e.
03:16
So this is anapace 1 of myosis 1...
