Even if the first mother is a carrier, isn't there always a possibility to have carrier only female progenies? I mean birth of each son/ daughter is an isolated event and there always exists a possibility of unaffected females by being a carrier...

Sunil Sir,
I went through a video on NPTEL course "Human Molecular Genetics" which is on pedigree analysis at this link :


http://nptel.ac.in/courses/102104052/5

Between minute 32 and 33 of the video professor says that the carriers in "x linked recessive condition" are denoted by a "dot within the circle". 
Can we challenge the question giving the reason that no clear indication is given if any of the females in the given pedigree are carriers thus X linked recessive condition was not indicative from the given pedigree. 

I think this reason should hold in favour of us because it is in the NPTEL cource lecture.

I also found a video and webpage at the below links explaining the same pedigree as in the gate question"

Hi Rahul,
I think there is nothing wrong in giving it a try. Assuming there is a cost associated with each review, why don't you people team up and each one in the team asks for the review of a question (which are in the circle of doubt)..
