Question

Some genomic representation of skin colour are given below
(i) AA bb CC
(ii)AA bb cc
(iii)AA BB CC
(iv) aa bb cc
Which of the option is correct for showing the darkness of colour of the skin in decreasing order?

• A. iii $\to$ ii $\to$ i $\to$ iv
• B. i $\to$ iv $\to$ ii $\to$ iii
• C. iii $\to$ i $\to$ ii $\to$ iv
• D. i $\to$ iii $\to$ ii $\to$ iv

Answer 1

The correct option is C iii $\to$ i $\to$ ii $\to$ iv

When there is a self-cross between AaBbCc, out of the 64 offsprings there will be of the darkest skin color, followed by a range of intermediate colors from dark to light. Of these AABBCC will be the darkest followed by AAbbCC, then AAbbcc and aabbcc. Thus the correct answer is option C.
