The allele for a widow's peak has complete dominance over the allele for a straight hairline (w). What is the probability of two parents heterogeneous for a widow's peak (Ww) having an offspring without a widow's peak?

Answer:

The chance of producing a widow's-peak offspring is 3/4. Widow's edge, which is a recessive trait, is a dominant trait over straight hairline.
