What is a widows peak?
A widow’s peak is a distinctive, V-shaped hairline that tends to run in families. Despite the myths, it’s probably no more significant than other genetic traits such as curly hair or a cleft chin. Some people prefer to downplay their widow’s peak and some want to show it off.
Which traits are dominant and which are recessive?
The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.
How rare is a widows peak?
There’s a fair amount of lore surrounding the widow’s peak — namely that it is a dominant hereditary gene and that it’s quite rare. These are both false, however. The widow’s peak is most visible when the hair is short enough to show the hairline or when it’s pulled back, like in a ponytail.

Is Widows Peak trait controlled by many genes?
Widow’s peak is sometimes used to illustrate basic genetics; the myth is that it is controlled by one gene with two alleles, and the allele for widow’s peak is dominant over the allele for straight hairline. There is no evidence that this myth is true.
