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 important about the peak wavelength of a thermal radiation spectrum?
The peak wavelength, is connected to the temperature of the objects. we have short peak wavelength when the temperature is high.

Formula for peak inverse voltage?
piv:the maximum value of reverse voltage across a diode that occurs at the peak of the input cycle when the diode is reversed-biased.
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.
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.
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.
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.

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?
None. Since it is dominant, both would have to show it to pass in on. If both show it and both have the recessive (straight), the child would have a 3:1 chance of showing it.
What is a witches peak?
I'm not sure. But widows peak is the little v-shaped hair part coming down on someone hairline. Although not everyone has one I'm pretty sure you mean a widow's peak, which is a dominant gene that gives you a peak of hair on your hairline on your forehead. It sometimes gives a slightly vampirish look to people. It also can be exaggerated by hair loss.
I wonder about the phrase widow's peak as architectural. Some old 1800 and early 1900 homes near the ocean had a look out tower on the top floor over looking the ocean. Is it a widows peak?

The "cheek" rhymes with "weak." A person who has a "Widow's Peak" (V-shaped point in the hairline in the center of the forehead) also has something that rhymes with "weak."
