Solution

The correct option is B If both the assertion and reason are true but the reason is not a correct explanation of the assertion
The genes that are carried on the Y chromosome are called holandric genes.
Holandric genes can only be passed by males onto their sons; they code for 'maleness' but sometimes cause rare conditions like hypertrichosis pinnae and color blindness.

Thus the correct option is answer B.
