can recessive genes go all the way back to a great grandparent?

Question

im just curious.. like if my greatgrandparent was redheaded, or blue eyed.. could i have that recessive gene in me somewhere or is it too far back?

Answer 1

Well I'm not a pro on the subject but I do know that its possible. My husband and I come from families with blonde as dominate. We are both blonde so we thought we would have a blond baby. Well until he came out. My son was born with red hair.

My husband's grandmother's mother had red hair. That making it my son's great great grandmother. We couldn't trace it to anyone else in the family tree.

So yes, it is possible.

Answer 2

Yes, they can go that far back. They don't get "weaker" as generations go, its just that you have to have two of the recessive gene in order for it to present, so you could be carrying one and the dominate gene is the one that presents. So if your partner also carrys the recessive gene, there is a chance it could present in your children.

Answer 3

Recessive genes can go back even further than that without being expressed. They would just need the right genes on both sides to express themselves.

Answer 4

yes . i have brown hair and eyes, olive skin so do all my cousins and siblings all there kids have the same b,eyes b,hair dark skin my oldest same thing so i was shocked when my girl came out with red (bozo) almost translucent skin and bright blue eyes she doesn't look like anyone in my family or my boyfriends family i am so sick of people asking us where the red hair came from so i reasurched it and it turns out that both my boyfriend and i had great great grandparents that were part irish how irish we don't know but it was enough to give her these traits although i get sick of all the comments about her hair and skin i have even had people ask me if shes adopted because we look nothing alike so yes thats the answer

Answer 5

you may have a by ability of lower back gene which works lower back some generations. eco-friendly eyes are very variety it is an similar in family members both blue or brown then my sister is the purely one with eco-friendly although the chemical to make eco-friendly eyes is likewise got here across interior the blue eye gene

Answer 6

That's definitly not too far back, i have red hair because of a great grandmother, she was the only other red head in my entire family and even after all the other babies born into my family since (i'm now 26) I'm still the only living red head :)

Answer 7

The short answer is yes.
The long answer is that the genes are passed from generation. Your genes came from your parents. Theirs from their parents. Therefore your genes came from your grandparents. Furthermore, your grandparents genes came from their parents and it goes on and on.

Answer 9
