Can two people with black hair have a kid with red hair?
If each parent with dark hair contributes recessive genes for blonde hair color in addition to genes on the MC1R gene, they could have a child with red hair.
Can a blonde couple produce black or dark haired children?
Blondes having dark haired babies would be rarer than brown haired parents having blondes, but like I said, the exact nature of genetically inherited hair colour, isn’t fully known. But I have a blonde son whose dad had jet black hair and I had very dark red/brown hair.
Is it possible for both parents to have blonde hair?
If both parents are blonde, they will certainly have a blonde child. Here, we know that both parents’ genotypes contain only blonde traits because that is the only way they could have blonde hair. A brown allele would have dominated, resulting in brown hair.
Is it possible for two blondes to have dark hair?
But two blondes couldn’t do that – they can’t have a recessive dark gene because if they had a dark and a blonde gene their hair would be dark as dark is dominant over blonde. It’s more that every parent carries both, but in long lineages of blondes the brown becomes the recessive gene.
Can a person with brown hair have blonde hair?
It also explains why two parents with brown hair can produce a child with blonde hair, as they both possess recessive blonde alleles in their genes, and as it is completely random which ones are passed on in the womb. And What About Red Heads? Red hair operates slightly differently to the other hair colors.
