1. Pedigree (question-45) (Possible Ans : "X- linked recessive inheritance or Y linked" and "Y-linked only") (Can give upto 2.66 marks)
2. Zero order rate kinetics (question- 49) (Possible Ans : "100" and "10000") (Can give upto 2 marks)
3. Cytokinesis inhibitor (question -18) (Possible Ans : "Cytochalasin D" and "Colchicine" ) (Can give upto 1.33 marks)
These 3 questions have possibility of giving a student 6 marks which can be really crucial.
Each of the 2 answers in the above question is proving to be right, thus all the students who have answered any of the 2 possible answers in the above questions should be given the benefit of doubt.
What is views from all of you guys, should we challenge all the 3 questions ?
For the Pedigree question:
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
Besides that
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".
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.
the google image of y linked inheritence as same as given question and u r explanation also perfect and the three questions are very meanful for challenge
