Being left-handed...does it run in the family?

Answer 1

It has to do with genes&chromasomes. you get ones set from mom and another from dad. each person has two genes controlling every characteristic they have. One gene is called a dominant gene, and there are other forms of the same gene that are recessive. If you get one leftie gene from mom, and a rightie from dad, then you will be right handed, since the rightie gene is domnant. You need both leftie genes to be left handed, since they are recessive, and can be canclled out by the dominant ones. (You'll learn all that wonderful stuff in Bio class!)
So to answer your Q, yes, if your family has lots of lefties, there is a good chance you will be one, too. However, you can still be left handed if there is little of it in your family:
ie) Both parents are righties, but both carry the recessive gene for being left handed. If, when you were conceived, you got the recessive gene from each parent, you will be a leftie.

Answer 2

I think through the males, but I'm not sure. My father was left-handed, I'm female right handed, and my son is left handed. Maybe in some families?

I know that mirror image identical twins, have one whose left handed, and the other is right handed.
It is also more common for males, than females.
And it could skip a generation too.

Answer 3

Depends. I'm left-handed, but the only other person in my family who is is my dad. Most people are right handed - this actually derived from ancient times - whadda ya know? I actually learned something in History class! - at feasts/any kind of dinners, people were to eat with their left hands. But they did everything else with their right.

Answer 4

I do not believe that they have found a direct link in the genetics yet. However I come from a family of almost all lefties, so I would say yes it runs in the family.

Answer 5

yes it does to some extent. My father is left handed as am I, but my sister and Mom are right handers. Think I read somewhere leftys make up about 13% of the population.

Answer 6

you would think it was genetic, wouldn't you, since alot of left handed ppl have a left handed parent or something. but actually, it really doesn't run in the family. its really just whatever you've always felt comfortable using, when you first tried out that pencil in kindergarten.

Answer 7

No, but I did read that women who have children in the later childbearing ages are more likely to have left handed children.
My dad's a lefty but no one else in our family is.

Answer 8

I say it does. Both of my children are left handed.
My sister is left handed and my husband's brother are left handed

Answer 9

I think that it does.I have a left-handed daughter.Her half sister is.The sister has 2 children who are.At least 2 of the daughters' aunts are.Seems like a lot for one family.

Answer 10

I am left-handed and no one else in my family is...Because of my case I don't think so, I relly don't know why I am left-handed but I like it:)
