0:00
And equals six.
00:01
So this is a dipole cell.
00:02
We have a dipole cell that has six chromosomes.
00:07
And the cell is heterozygars for g .a.
00:11
And homozygars dominant for b.
00:15
And homozygars recessive for d.
00:18
And g and a and b are on the same chromosome.
00:21
So then you can see that we have two chromosomes.
00:24
This is one copy.
00:26
This is another copy.
00:29
Now let's use the same color.
00:33
A and b on the same, and a is a heterozygars.
00:38
So this means, let's say, a, capital a, and then this is lower a.
00:43
And b is homozygars dominant, and so b is on the same chromalum, let's say, capital b and b, capital b.
00:53
And then d is on a different chromosome, and then d is homozygars recessive.
00:59
So let's draw a different chromosome right here.
01:02
This is the centromere and d again is homozygous recessive so let's say lower d and lower d and then you should have a third one that doesn't mention any gene so let's say you have a total of six now from there you can see that draw the cell with following stage first you want to draw a anaphase of mitosis so during anapace so all the chromosome will copy first and then they'll actually pull towards the opposite side.
01:43
So for example, for each chromosome, you will have, you will have a, this is two copy, b, b, this is second, lower a, lower a, capital b, capital b.
02:07
That's the first chromosome.
02:08
The second, first two, homologous pair.
02:12
The second is d -d and d -d.
02:17
And c, the third one, you won't be able to have any marker, but this is a centromere connect in the middle.
02:27
So you can see for each chromosome, you have two copies now.
02:30
They are called cysticromatids, and then i put the allure on top of it.
02:36
So in our end phase, the two sister chromatids separate from each other.
02:41
So basically, you'll have, this is my tautic spindle.
02:47
And you have the first chromosome here, a, b, and this is the other one, a, b, both capital.
02:59
And then you have the second, lower a, capital b.
03:09
Just say that lower a, capital b.
03:22
And then the third one, d, d, and then fourth, d.
03:40
And the last one, you can't really tell.
03:56
So you can see for each daughter cell, it will end up having six chromosome.
04:05
So the top row goes into one cell, daughter cell, and the bottom goes into the other one, and they are identical.
04:13
Each has six chromosome.
04:16
So you can see that they are identical.
04:18
So this is anifice.
04:20
Now, let's talk about the second one.
04:24
Anaphas 1 of myosis.
04:31
Enophis one of myosis, the feature is the homologous chromosome pair separate from each other.
04:47
So this means that if you go back, these two are called homologous pair.
04:54
One inherit from father, the other inherit from father.
04:58
So in anifice 1, these two actually separate each other.
05:02
So you'll see that you have two cysticromatids to attach to each other.
05:08
One has capital a, capital b, and then the other one is lower a and capital b.
05:22
And then same with these two separate each other.
05:32
D, d, d, and d.
05:38
So this is a homologous chromosome pair...
