A widowâ??s peak, or widowerâ??s peak for men, is a distinctive hairline that features a v-shaped point of hair growth on the forehead. The term is surrounded in superstition. One explanation of the term â??widowâ??s peakâ?? is from the early 1800s. It was believed that a person who had this type of hairline would outlive their spouse. The belief possibly came to be due to the aging process and receding hairline that can come with age.

Could 2 people with a widows peak have a child with a straight hairline and could 2 people with a straight hairline have a child with a widows peak EXPLAIN?
Yes to the first one, no to the second one. Firstly, widow's peak is caused by a dominant gene while a straight hairline is caused by a recessive gene. Let 'H' be dominant and 'h' be recessive. So for a dominant gene, the trait still will be expressed whether the genotype of the person is homozygous dominant(HH) or heterozygous(Hh). For a recessive gene however, the trait will only be expressed when the genotype of the person is homozygous recessive (hh). So two people with a widow's peak CAN have a child with a stright hairline, provided both of their genotypes are Hh. This is because by crossing their genotypes, they can have a possibility of having child with the genotype HH(widow's peak), Hh(widow's peak), and also hh(straight hairline). The ratio of these three possibilities however, are 1:2:1. So the odds of having a child with a straight hairline in this case is 1:3. If the two people who have widow's peak have the genotype HH or one of them HH and the other Hh, then the possibility of having a child with a straight hairline is 0. This is because by crossing their genotypes together, the genotype of the child will either be HH for the first case, and HH or Hh for the second case. For two people who have a straight hairline, the genotype of both will definitely be homozygous recessive (hh), thus child will definitely have the recessive gene. Therefore, it is not possible for two people with straight hairline to have a child with widow's peak.

What is a 'widow's peak?
Widow's peak is a V-shaped point in the middle of the hairline (above the forehead) ((:
In humans widow's peak (W) is dominant over straight hairline (w). If a heterozygous male marries a female with a straight hairline what percent of their children can be expected to have widow's peak?
50% of their children are expected to have a widow's peak. When a heterozygous male (Ww) with a widow's peak gene marries a female with a straight hairline (ww), their offspring have a 50% chance of inheriting the widow's peak gene from the father.
Is a widow's peak forehead hairline or a straight forehead hairline more dominate?
A widow's peak hairline, characterized by a V-shaped point at the center of the forehead, is often considered a dominant trait compared to a straight hairline. Genetic studies suggest that the widow's peak is influenced by a single gene with dominant alleles. Therefore, individuals with one or both copies of the widow's peak allele are more likely to express this trait, making it more prevalent in certain populations.
Why are a window's peak considered a single gene trait?
A widow's peak is a dominant trait, so even if a person has both the widow's peak and the straight hairline trait, only the widow's peak will be visibly apparent.
Is a curved hairline a widows peak?
No, a widows peak is when the front of your hair is in a V shape, receding hairlines create "widow's peak"
What is a Widow's Peak in Wicca Beliefs?
A Widow's Peak is a style of hair, where the hairline recedes at the temples, as depicted by Bela Lugosi's Dracula. It has no bearing on, or relation to, Wiccan beliefs.
If AA is dominant for a widow's peak and if a child is born without a widow's peak what is his phenotype?
The Phenotype would be a straight hairline. The genotype would be aa.
Why is a widows peak called a widows peak?
A widow's peak is named for its distinct shape, resembling a peak or V at the center of the hairline on the forehead. The term is believed to have originated in the 19th century, with some associations linking it to the image of a widow mourning, as the peak was thought to symbolize a woman's sorrow. The name reflects cultural perceptions rather than any specific characteristic of the hairline itself.
What is a physical characteristic such as height or hair color or widow's peak?
A widow's peak is a V-shaped point in the hairline near the forehead. It is a genetic trait and can be more prominent in some individuals than others.

A widow's peak is a V-shaped area of the hairline in the center of the forehead The allele for having a widow's peak is dominant to the allele for not having a widow's peak If two parents do not hav?
If two parents do not have a widow's peak, it is possible for their child to inherit a widow's peak if they both carry the dominant allele for it. This would mean that both parents are heterozygous for the widow's peak trait.
What Nationality of people has a dominant gene for widows peak?
Widow's peak hairline is not determined by nationality, but rather by genetics. It is inherited as a dominant trait, so individuals with at least one parent with a widow's peak are more likely to have one themselves. It can be found in people of various nationalities.
