If two brunette parents both have a recessive blonde gene, there's a 25% chance they'll each pass down their recessive gene, resulting in a blonde child.

Can two parents with dark hair have a blonde child?

It turns out that brown hair is dominant. That means that even if only one of your two alleles is for brown hair, your hair will be brown. The blond allele is recessive, and gets covered up. If two brunette parents have a blond child, they had to have instructions for making blond hair hidden in their DNA.

Which parent determines the hair color of baby?

Human DNA has millions of on and off switches along networks that control how genes function. Genes responsible for hair color come from both parents. Although the genes passed down from a child's parents determine hair color, variations can result in a child having a different hair color than both parents.

How do you get a blonde baby?

Is black hair or blonde hair more dominant?

One explanation is that as dark genes are more dominant, when you compare them to the ones responsible for the lighter colors. Due to this reason, when one parent carries the dominant dark color gene, and the other has the recessive blonde gene, the chances of their children having dark hair is extremely high.

What causes blonde hair?

Natural blonde hair, is caused by a lack of a pigment called eumelanin. This pigment deficiency is what gives blondes their hair color. The general explanation as to how blondes came into being, is related the need for Vitamin D and lower levels of sunlight in some regions.

Can two blondes have a brunette?

Since brown hair is a dominant trait, at least one of the parents would have to have brown hair. But since they're both blondes, the brunette gene can't exist, otherwise the parents would have shown brown hair. While brunettes can have blonde children, blondes cannot have brunette children.

How many babies are born with blonde hair?

According to LiveScience, most kids that are born blonde — even the most platinum babies — shift to brown hair by the time they turn ten.

Can two brunettes have a ginger baby?

Is blonde or red hair more dominant?

Red hair is not actually a recessive gene (like blonde is), but is rather an "incomplete dominant." In the world of genes, there are dominant genes, which take over any recessive gene (brown, black), recessive genes (blonde), which will be taken over by any dominant gene, or incomplete dominent genes (red).

Are gingers going extinct?

But whatever happens, redheads will not be going extinct. They will almost certainly decrease in numbers but there will always be a few around. And luckily for redheads, their numbers will probably never get all the way down to 6 or 7 million.
