Please read the following scenario to answer the following question(s).
Widow's peak, a pointed hairline on the forehead, is a genetic trait caused by a dominant allele. It can be traced back through a family's history using pedigree analysis. The pedigree shown here shows three generations of a family. Notice that some individuals (shown in gray) have a widow's peak (W = dominant allele and w = recessive allele).

-This pedigree supports the fact that widow's peak is due to a dominant allele,because if it were due to a recessive allele and both parents show the recessive phenotype,then ______.
A) none of the sons would have a widow's peak
B) all of the offspring would have a widow's peak
C) none of the daughters would have a widow's peak
D) all of the daughters and none of the sons would have a widow's peak
