Question

The allele for a widow's peak hairline (W) is dominant, and the allele for a straight

hairline (w) is recessive. If both parents are heterozygous (Ww) for this trait, what is the
probability that their child will have a straight hairline?

Answer 1

I don't like using W instead we can try to use R 'kay?

R - Dominant

r - Recessive

75% chance that they will have widows peakline children. 25% chance for straight hairline
