Hello student here.
00:01
The question is about a mouse and these mouse having the somatic cell and these somatic cells having the 20 pairs of chromosome.
00:13
So in case of secondary ucite, so the secondary ucite having how many chromatid.
00:24
So we have to tell about the number of chromatids or we can say the sister chromatid in case of secondary usyte.
00:34
So if we talk about these somatic cells, we know the somatic cells having the 20 pairs of chromosome in case of this mouse.
00:43
So the germ cells is also having these 20 pairs of chromosome.
00:49
And these 20 pairs means simply the 40 chromosomes.
00:55
So these germ cells undergoes the process of the ugenesis.
01:00
And in the ugenesis process, this secondary ucite as well as overmobile form.
01:07
So this is ugonia and this is the 2n.
01:12
So by simply developmental process it undergoes the mitosis and form the primary ucite.
01:19
So these primary ucite is the deployed in nature.
01:25
And after this this primary usite undergo the meiosis one and this is a kind of reductional division.
01:33
So in this reductional division the chromosome number will be half.
01:38
So this is going to form the secondary usites and these secondary ucied having the haploid number...
