The allele for a widow’s peak has complete dominance over the allele for a straight hairline (w). What is the probability of a man with a straight hairline (ww) and a woman with a widow’s peak (WW) having an offspring without a widow’s peak?

Answer:

Step-by-step explanation:

Because the woman has both widow’s peak alleles (WW) and the allele for a widow’s peak (W) has complete dominance over the allele for a straight hairline (w), her offspring is always going to have a widow's peak. So the probability of having an offspring without a widow’s peak is zero.

Step-by-step explanation:

Offspring 1= Ww

Offspring 2= Ww

Offspring 3= Ww

Offspring 4= Ww

Since the allele for widows peak is dominant and all offspring will have the allele they will all have that trait.
