Is it possible for a man with black hair and a woman with blonde hair to have a child with ginger hair?

serious answers only please.Is it possible for a man with black hair and a woman with blonde hair to have a child with ginger hair?
Lets say black and blond are dominant hair colours and ginger is recessive. We can draw a punnets square to determine your answer.





D - dominant d - non dominant


*** Remember, you only need one dominant gene for it to show!!!

Two recessive genes would give you ginger hair, so yes, ginger hair can come from two people with black and blond hair. (But somewhere before this generation must have had ginger hair, it cannot randomly pop up)Is it possible for a man with black hair and a woman with blonde hair to have a child with ginger hair?
it is possible but usually, black hair is dominant to blonde hair. the situation you mentioned is ';incomplete dominance'; which assumes the traits of both parents are blended together. in reality though, most characteristics are not blended. Regarding hair color though, it is determined by multiple traits rather than just one gene.
If either the man or the woman have ginger haired parents, there is a chance they're carrying the gene (they'd be heterozygous) But if that's the case, the child would have to get the recessive gene from both parents to turn up red-haired (homozygous recessive). And even that's assuming red hair is a recessive trait, I'm not sure if it is or not.
Unless you know that there is incomplete dominance (no one variation of the hair color gene is dominant over the other) this is not possible. You either get black hair (which is more likely because it's dominant) or you get blonde hair. In flowers, for example, incomplete dominance occurs and colors can mix.
It is possible, because the man with black hair or the woman with blonde hair could be carrying a recessive red hair gene, which means their children could have a 25% chance of being gingers
yes...there are specific genetic codes for everything...although it is more likely that the child will have black or blonde hair
Yes. Just look at Prince Harry
yea because your trait for hair might not be from either of you or the fertilzee
