can they give birth to a child with blonde hair that eventually around the age of 8 turns into a darker blonde???



i know that with the punett square, the kid must have dark hair, in this case black, but could the kid be born with blonde hair that eventually turns dirty blonde?



thanks!

Genetically speaking, no. BB always dominates bb. If the child did have blonde hair that would mean the dark haired parent was not BB, but was actually a carrier and was instead Bb.



Hair color, I believe, is actually based on several genes just like skin color and is not as simple as say, eye color. However, based on your simple analogy the answer is still no.



Or the blonde mother cheated on the dark haired father with a blonde, which would result with a blonde child. - Hey it could happen these days. lol.

Thanks, but please don't disown your mother just yet. Hair color is on a spectrum unlike eyecolor. It eould actually be a much more complex punnet square, ie. BbBbBb instead of just Bb. Report It

It really shouldnt happen, when you just look at BB's but it does. I am one of those myself. As a yound child up to about age 6 or 7 i was completely blond, where my mother has no blonde family memebers at all. My father has dark hair but many blonde family members. My brother has very light hair still, but white blonde as a child, and my sister has very light brown, with blonde streaks. This definitetly happens.

Using the information of just that gene, no. The child should be born with dark hair. But the child will be a carrier of the blond gene, so the child's children could have blond hair.



But I believe there are much more than just one gene that controls hair color, so in reality is probably is possible.

Well, Due to recent reaserch, doctors recently realesed a statement saying that mothers are 96% of birth, so, the kid will have the same color as their mothers.

The child will be born heterozygous dark-haired (Bb), so the child will not ever have naturally blond hair. However, if the parents were Bb and bb or there was a mutation, the child could be blonde.



As for hair that darkens, it is very common for blonde hair to be brighter during childhood and darken with age.

If it were controlled by a single trait, no. There are a number of other genes involved, and expression is not always constant throughout life.

it can't happened according to research.child will have black hairs only.
