So, okay, let's go through the question.
00:02
In the question we are given with a pedigree and in this pedigree we have to find out the genotype of both the parents, that is the father as well as the mother.
00:14
In the generation 1 we are given as a male is married with a female and in this case male is affected, that is it is diseased.
00:30
These lines depict diseased male or affected male and on the other hand the female is absolutely normal, right, that it is not diseased.
00:43
Also, we are given that our trait or our disease is x -linked dominant.
00:54
Dominant in the sense that it can be expressed in both heterozygous and homozygous form.
01:02
So, the disease is x -linked dominant.
01:05
Now, let me explain to you what the word dominant implies to, right.
01:11
So, if a trait is given as a dominant trait it can be expressed in heterozygous form...
