Transcript

00:01 Hello everyone, in this question here we have been given the pedigree chart.

00:05 So, here the male is affected and the female here is also affected.

00:11 And so, therefore, we can here see that their children are also infected.

00:17 And here is a male child who is not infected.

00:22 Then there is another couple here in which the male here is affected and the amongst the children here the male is affected and these two are now married and their children are completely normal.

00:42 So, here we have been said that the characteristic is dominant or recessive.

00:47 So, here it is said that the characteristic is dominant or recessive.

00:53 So, let us see here.

00:54 So, for that first of all let us understand whether it is an autohomal or sex -linked disease.

01:00 So, let us first of all analyze that this here is the x -linked recessive disorder.

01:06 So, that means this must be.

01:07 For that let us consider that this is an x -linked disorder.

01:11 So, that means this here must have been the affected x chromosome and here also there is affected chromosome.

01:20 So, this also must have been affected and this also must have been affected and it is not possible for this child to be not affected because both of the parents are affected.

01:32 So, that means here this is not the x -linked disorder.

01:36 So, this here is an autohomal disorder...
