Question

13 multiple choice 1 point a mother has a widows peak on her forehead in her hairline ww and dad has a straight hairline ww. what are the chances that their four kids will have a widows peak? 100% or 4/4 25% or 1/4 75% or 3/4 50% or 2/2

Explanation:

Widow's Peak (W) is a dominant trait. The mother has genotype WW (homozygous dominant) and the father has genotype ww (homozygous recessive). When they have children, all offspring will receive one 'W' allele from the mother and one 'w' allele from the father. The genotype of all children will be Ww. Since the presence of the dominant 'W' allele results in a Widow's Peak, all four kids (100% or 4/4) will have a Widow's Peak.

Answer:

A. 100% or 4/4
