Does the Widow's Peak only Occur in women?

Question

Or is it only less likely for men?

I'm pondering this because I have a Widow's peak. Yet my brother does not. And I have read that it is the dominant trait. And none of my family has it, which leads me to believe that my father had the gene. ( I have never met him.) So, my question is, does it only commonly appear in women? Is it equal? Or is something strange going on here?

Ahahah. I took Biology last year and I forgot about most of the things.

I'm such a good learner.


You see, now that I think about it, it makes sense.

I'm just not good at remembering things. xP

Thank you, though.

Answer 1

Men have them too, it's only a term for the hair pattern

Answer 2

men and women get them all the same. the only thing is, that genetically, men tend to get their hair patterns from their mothers, not their fathers. also, just cuz it's a dominant trait, doesn't mean you'll get it. remember the punit square???

if W= widows peak and w= not widows peak, than here are the potential possibilities of having it: WW, Ww, ww
the ww will occur in people who's parents either both had a Ww or one parent had WW and the other had ww. generally there is always a 25% chance of you getting some dominant trait in your parents.

just because your brother doesn't have it though doesn't mean that someday when he has kids, his kids won't. it still may be encoded in his genotype somewhere and that very well might be something that shows up in his son or daughter. his son most likely, though, if his wife has a widow's peak. that's how it tends to happen. but not all the time. sometimes there are other factors like mutations and stuff.

Answer 3

The widow's peak is an autosomal dominant gene, which means that men and women are equally likely to get it. Assuming your dad carried one (dominant) widow's peak gene, and one (recessive) non-widow's-peak gene, and your mother did not carry the WP gene, then each child would have a 50-50 chance of inheriting the WP gene and therefore have the widow's peak.

Answer 4

Men have them. If you have it, and none of the rest of your family has it, and you've never met your father, and it is a dominant trait, then it would reason to believe that your father had it, but also had the recessive trait which is why your brother does not have it. It occurs equally across sexes, and the extent to which it is visible depends on a lot of things... hair color, other genetic determinants for hair pattern, forehead size, etc.

Answer 5

I just finished learning about genetics. I don't believe it occurs in men. I have never seen a guy with a widows peak. I think it's a gene that is carried by the male and shows up in the female. That's what I think.

Answer 6

No. Guys and girls have it.
It's not a sex-linked trait.
If no one else in your family has it, it's because there's an independent chance of each person not getting it (assuming only your father carried the gene). So, you got the % with the gene, and your brother is the % without it.

it works like this: each parent has two traits. They pass one along.
ex:
R= widow peak r= not

dad=Rr mom=rr

rr + Rr = 1. rR 2. rr 3. rR 4. rr = 2Rr's and 2rr's

OR

Dad=RR mom=rr

RR+rr = 4 Rr's.

So, obviously, (if you and your brother share a father), you dad was Rr, because if he was RR you would both have widows peaks.

Answer 7

It's equal,from what I've seen.I have a widow's peak,my son inherited it from me whereas my daughter did not.Many people in my family have one,guys and girls alike!

Answer 8

my dad and younger brother have widow's peaks.

Answer 9

Men have them too..if one of ur parents didnt have it, it may be reccesive and it was passed to you..maybe ur grandparents had them...

Answer 10

Men have them too.
