Hi, according to the given question, it says that species a is having 2n is a chromosome and species b is having 2n is 14 chromosomes.
00:18
So we have to find out the number of chromosomes in the given conditions.
00:22
The first condition is allotriploid condition of ab.
00:31
So here for allotriploid, let us consider a is haploid and b is diploid.
00:43
So in this case, we get, when 4 is added with 14, we get 18 number of chromosomes.
00:50
And another case is where a is diploid and b is haploid.
00:58
In this case, we get 8 is added with 7, total number of 15 chromosomes.
01:04
So allotriploid offspring of av gives 18 and 15 chromosomes.
01:11
Now, the second part of the question is auto tetraploid offspring of a.
01:20
Autotetraploid of 8.
01:24
So this means that the deployed organisms is multiplied with 2.
01:31
That gives 8 multiplied with 2 total of 16 chromosomes.
01:37
So this gives 16 chromosomes.
01:40
Then the third is allot tetraploid offspring of ab.
01:58
Of ab.
02:01
So in this case, three possible conditions are generating.
02:05
So first is 2n from both species that gives 8 added with 14.
02:15
This gives 22 number of chromosomes...
