A Windows Peak is AV shaped area of a hairline in the center of the forehead an alley for having a widow's beak is dominant to the alley for not having a widows beak if 2 parents do not have widows beaks what is the possibility that their child will have a widows beak?
If both parents do not have widow's peaks, it is unlikely that their child will have a widow's peak. Widow's peak is a dominant trait, so if both parents do not express the trait, it is unlikely that their child will inherit it. The probability of their child having a widow's peak would be very low, unless there is a spontaneous mutation or genetic variation.
what would be the percentage?
If both parents do not have widow's peaks, they would both have the genotype ww (where w represents the absence of the widow's peak trait). Since widow's peak is a dominant trait (W), they would not be able to pass on the trait to their offspring.
Therefore, the genotype of their child would also be ww, and the child would not have a widow's peak. So, the probability of their child having a widow's peak would be 0%.
