Blonde or brown hairr?

Blonde and brown are both very nice! Try both.


If a child has blonde hair and both the parents have brown hair what does that tell you about the allele for blonde hair?

It tells you that even though the parents have brown hair, they have a recessive allele for blonde hair also. And even though brown is suppose to be visually dominant, it is not the case at all. Two brown heads can make a blonde or brown, and of course even red haired child. Another way to look at it may be the parents have the following alleles for hair color: (b,b) - (b,b) in which case the dominant allele is Blonde or Brown.


If both parents have brown hair and eyes can there baby have blond hair and blue eyes?

yes it is very possible. it all has to do with a gene pool but simply YES! -Actually, it is theoretically impossible. Blonde hair is a recessive trait, so both alleles must be the same, represented here as "hh". In order for the eyes to be brown, a dominant trait must be present, represened as "H" here. So it would either have to be Hh or HH. However, if both parents have blonde hair, there can only be two "hh"s in the gene pool. When the egg is fertilized, the only possible traits on the gametes are "h"s. There can be no dominant genes, since both parents have blonde hair and the brown hair gene would mask the recessive blonde gene. And the same goes for eyes, since blue is recessive in eye color and brown is dominant. The blue eyes are indicated with a "bb", and brown eyes as either "Bb" or "BB". Since both parents have blue eyes, the only possibility for each parent is "bb", and each parent giving on allele means one parent can give b or b, and the other parent can only give b or b. No matter how it goes, the end result will always be "bb". So to summarize, no. Two parents that display a recessive trait always produce an offspring showing that trait. Two brown-haired brown-eyed parents can, however, have a blonde-haired blue-eyed child, if both parents are heterozygous, meaning have "Hh" and "Bb". I hope this answer made sense to you, and that I explained it well and didn't ramble to an excessive degree.


If a child has blonde hair and both of her parents have brown hair what does that tell you about the allele for blonde hair?

It means the freckle trait is recessive. For example, if the allel for freckles is 'f', then the parents must have 'Ff' and both sent a 'f' to the offspring.If one sent a 'F', then the child would have freckles.OMG, gotta tell my science teacher about that, cuz we're learning about traits now and I'm shocked that I knew that!


Can both brown eyed parents have 2 brown eye children and one child with green eyes?

It really depends on genetics down the parents line. Brown pigmentation on the eyes is a dominant allele on the gene and where 2 brown eyed parents reproduce, there is a high chance that all children will have brown eyes. However, if both parents carry a gene for blue eyes, which is recessive, there is a chance that both genes will meet and create off spring with blue eyes. This is known in laymans terms as a 'throw back', i.e. some one on either genetic line has had blue eyes. So yes, it is possible for parents with brown eyes to have 2 children with blue eyes and one with brown.


Can parents with black hair produce a baby with brown hair?

Sure, both of my grandparents had black hair and they had six children, about half had brown.


What are the odds of having blonde hair and brown eyes?

It depends on the parents. It should be about 3 out of 16 times, if the parents are heterogeneous for both traits. If both parents have blonde hair, you are certain to be blonde. It is hard to tell with the eyes to know if both parents carry a recessive gene or not. But there is more than genotype to consider here. In this case, if the genes in question determine melanin-making capacity, then this would actually be impossible, since melanin is needed both for eye and hair color. It that case, they might end up with green eyes (blue eyes with a layer of theomelanin).


Can a baby come out blonde if you are brunette?

There is a possibility the child can come out red or blonde if both parents are brunette.


Can to blue eyed parents have brown eyed children?

no they cannot because if you have blue eyes, your alleles are bb, and so... bb and bb have no B, and therefore, with no dominant gene, there cannot be a brown eyed child.


My mom n i have dark brown hair my dad has black hair both my grandparents have dark hair my boyfriend n his sister have light brown hair n his mom has blond hair what color hair will the baby have?

If the females parents both have dark brown hair and the males parents both have light brown hair, their is a 50/50 chance of having either colour hair. Although if that is not the case, the child could have blonde hair if one of the grandparents has blonde hair also, there is not a definite hair colour. It is all down to chance.


What are Chris Brown's parents' nationality?

Both of Chris Brown's parents are African-American


Can a white mother and mixed father have a white and blond baby?

Yes, they can have a baby with blond hair if the mother has the gene that produces blonde hair (recessive) and also if the father has the same gene. It would be best if they both had blonde hair, but two people with brown hair can still have a blonde haired baby. It all depends on the genes that the parents received from their parents.
