Is a widows peak a trait controlled by many genes?

A widows peak is controlled by one gene that is passed on from both parents. In this case lets say your parents both have a dominant allele for a widows peak(A) so in that case, you would have a 100% chance of being born with one.


How many genes are passed to the offspring for a trait such as a widows peak?

6


In humans widows 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 a widows peak?

According to Mendelian genetics, if the male is heterozygous for the widows peak trait (Ww) and the female has a straight hairline (ww), 50% of their children are expected to have a widows peak (Ww) and the remaining 50% of their children are expected to have a straight hairline (ww).


If both of your parents have a trait are you guaranteed to also inherit that trait?

No it is most likely but it is not guaranteed. Both of my parents don't have widows peaks yet i have a widows peak.


If the mother is heterozygous for a trait like widows peak what are the chances that the eggs she produces will have the gene for a widows peak?

Half her eggs will have the widow's peak gene, and the other half will have the other allele, so it's 50%.


Is widows peak a dominant or recessive trait?

Widow's peak is a dominant trait. This means that if a person inherits one copy of the gene for a widow's peak from either parent, they will have a widow's peak.


What is the duration of Widows' Peak?

The duration of Widows' Peak is 1.68 hours.


Is a widows peak a sign of intelligence?

I've never heard that it is, however there's an English Old Wives Tale that when a woman has a widows peak, it means she will outlive her husband! I have been cursed - cursed NOT blessed - with a widows peak, I get accused of loosing my hair! I hate it so much, but love at the same time that it's so different!


When was Widows' Peak created?

Widows' Peak was created on 1994-05-13.


How can two parents with a dominant trait like a widow's peak have a child with a recessive straight hairline?

Yes, because they can carry the trait from their parents. You would need to look at the grandparents on both sides. If one grandparent on the maternal and one on paternal side had a widows peak then the parents could both be a carrier to the widow peak gene (wW), meaning they could produce a child with a widows peak. However, if both the maternal and or paternal grandparents lack a widows peak then it is impossible for a grandchild to have a widows peak because both parents would be recessive ww (straight hairline). When attempting to figure out genetics it is best to observe three generations for family genetic traits. However, when in doubt you should confirm with a paternity test.


Is a widows peak dominant or recessive?

A widow's peak is a dominant trait. This means that if one parent has a widow's peak, there is a higher likelihood that their offspring will also inherit this trait. If both parents have a widow's peak, the offspring will most likely have one as well.


If both of your parents don't have widows peaks is it possible for you to have a widows peak?

Yes, it is possible to inherit a widow's peak even if neither of your parents have one. Genetic traits can skip generations or be the result of a combination of different genes. So, it is within the realm of possibility for you to have a widow's peak even if your parents don't.
