Hi, in this question we need to find out the correct option regarding this pedigree which is shown in this question.
00:09
In this we need to find out the genotype of fourth number individual.
00:18
So let's start.
00:21
There is, as you can see, female is affected.
00:26
So we can say she is homozygous dominant with x capital a, x capital a, x capital a, when mates with the normal male which is showing normal genotype.
00:44
After that as you can see first that is the fourth number.
00:53
In this we need to find out this genotype.
00:56
That female when made with the male the progeny is like one affected male one normal female, one normal male and one is showing normal female.
01:22
So we need to find out the genotype of fourth number.
01:28
So as you can see, mother is affected.
01:31
So it is showing x -linked dominant case...
