Can a woman with natural blonde hair and her husband (with dark brown hair) have kids with blonde hair?

Answer 1

Yes.

Blonde hair is a recessive gene, linked to a number of chromosomes. For simplicity's sake, assume it's just linked to one pair. The fact that it's recessive means that if only one chromosome out of the pair is blonde (and the other is brown), the person will have brown hair. Each person then contributes one chromosome out of that pair to their children. So two people with brown hair whose chromosomes are Blonde-Brown could have a child with blonde hair (if they both give the Blonde gene).

Since you have naturally blonde hair, your chromosomes are Blonde-Blonde, so the child's hair color will depend entirely on your husband - that's why someone said the odds are 50%. In fact, multiple genes determine hair color, so that isn't quite correct, but you get the idea.

Answer 2

Well, that depends on the dominant and recessive genes.. i think a woman with natural blonde hair and a husband (with dark brown hair) CAN'T have kids with blonde hair.. cuz usually dark colors are dominant and so the children have about only 20% chance to have blonde hair

Answer 3

Yes, however the dark haired individual (your husband) must have a recessive gene for blonde hair in his family. The "dark hair" gene is a dominant gene over the "blonde hair" gene. I have dark hair and brown eyes. My husband has blonde hair and blue eyes. One of our children has dark hair/brown eyes. Two of our children have blonde hair/ blue-green eyes. This happened because my paternal grandmother had blonde hair/blue eyes. Hence a recessive gene for blonde hair/ blue eyes was on my side of the family (me being the dominant gene person). Genetics is so fun isn't it? Good luck!

Answer 4

Yes, if he carries the gene for blonde hair.

If he only has brown genes, then you will end up with brown.

Anyone who says they can tell you the odds is mistaken unless they have detailed genetic/family info about your husband.

Even if you had 5 brown haired kids with him, he could still carry the blonde gene and you wouldn't know.

Answer 5

The way it was explained to me:

Each person possesses a pair of genes for the trait, one from the mother and one from the father. To map it out:
B=Brown (Dominant, so if the pair contains any B, it will result in brown hair.)
b=Blonde (Recessive, so the person has to receive the recessive trait from both parents for it to show up.)

So, you'd be bb -- since you have blonde hair, you received a recessive gene for blonde from both parents.

Since your husband has brown hair, he has either BB (two contributions for brown) or Bb or bB (the combinations that would be a blonde from one parent and a brown from the other).

So if your husband has BB, no blond kids. But if he has bB or Bb, AND if he happens to pass on the recessive gene, then you'd have blond children (because you can only pass on b).

Possible combos (and someone correct my math if it's wrong -- I think each possibility of his genes yields another set of possible offspring):

Assuming: You (bb) + Him (BB)
Four different combos, all resulting in brown hair.

Assuming: You (bb) + Him (bB)
Four combos, two resulting in brown, two in blond.

Assuming You (bb) + Him (Bb)
Four combos, two resulting in brown and two in blond.

So, I think if we don't know if he has any recessive blond genes, we have to account for all the possibilities (combos and possible genes in the guy), so altogether the possibility is 4 in 12, or a one-third chance. But if we know or assume he has a blond recessive gene, it becomes a 50 percent chance. There's really no such thing as being "dominant for blond" if there's a brown-haired parent in the mix -- unless you mean blond passed down from both parents equals blond hair.

These combos also tell us that it's possible for two brown-haired parents to have a blond child, but it's not possible for two blond parents (natural, of course) to have a brown-haired offspring.

Hopefully that all makes sense.

Answer 6

It's all about genetics and dominate and recessive genes.

I have medium brown hair and my husband is blond (with a red beard) , and our son has red hair. Who would have thought?

It's always possible have a blond-haired baby.

Answer 7

No it depends upon dominance and recessives of genes. It may appear in the first generation or may not appear but in subsequent generation it must appear there due to Mendelian purity of gametes.

Answer 8

People who both have brown hair can have kids who are blond.
Often the characteristics of someone have skipped a generation and can be found not in the parents, but in the grandparents and their siblings

Answer 9

If the woman's blonde hair genes are dominant, then the child's hair will be blonde. = : )

Answer 10

YES IT IS, I HAVE BLOND HAIR AND MY KIDS FATHER'S HAIR IS DARK BROWN AND TWO CAME OUT WITH BLOND HAIR AND THE OTHER TWO CAME OUT WITH DARK BROWN HAIR.
