I found the below images from book :
Genetics : A conceptual Approach by Benjamin A Pierce
Image 1: Shows the standard symbols used in pedigree chart
Image 2: Shows a pedigree chart which is somewhat similar to the gate question pedigree chart
I went through a video on NPTEL course "Human Molecular Genetics" which is on pedigree analysis at this link :
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".
We can 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 these should make a strong case for review of Pedigree question and hold in favour of us because it is in the NPTEL cource lecture as well as a standard book.
yes u r right
