Answer 3

This is a question which has answer in heredity of biology.
mom=Bb
dad=Bb
B is dominant b is suppressed
So the combinations are BB, Bb, bB, bb
so the out of these four only brunette hair has one bb.
so if there is 50, the result will be, (50/4)(1)=12.5.
as it is nearest integer, so answer is 12.
