Hairline shape is an inherited trait in humans. The widow's peak allele is dominant and straight line is recessive. Predict how both parents with widow's peak hairlines could have a child without a window peak hairline.

If both parents have a peak hairline there child could still have a straight hairline because he could receive 2 recessive alleles for a straight hairline.

Both the grandparents could've had heterozygous alleles and they showed up in the grandchildren.
If they both have a allele for strait hairline
If they both have a recessive straight line allele.
the recessive allele would show through because there would be two of them.
because the parents have a dominant trait.
