If both parents have blonde hair why can their children have brown red or very dark hair?
Children can inherit hair color from a combination of genes contributed by both parents, including recessive and dominant traits. Even if both parents have blonde hair, they may carry hidden genes for darker hair colors, which can be passed down to their offspring. Additionally, genetic variation and mutations can also lead to unexpected hair colors in children. Thus, the diversity in hair color can result from the complex interplay of multiple genes.
What else can I help you with?
Blonde or brown hairr?
Blonde and brown are both very nice! Try both.
Do blondes have to have blonde parents?
No, blondes do not necessarily have to have blonde parents. Hair color is determined by a combination of genetics from both parents, and it is possible for a child to have a different hair color than either of their parents.
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!
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.
What percent of the offspring of brown haired parents who carry a recessive gene of blonde hair will have blonde hair?
If both brown-haired parents carry a recessive gene for blonde hair (genotype Bb), they can produce offspring with the following combinations: BB, Bb, Bb, and bb. The only combination that results in blonde hair is bb. Therefore, 25% of the offspring will have blonde hair.
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.
What color hair and eye will a baby have if the father has strawberry blonde hair and brown eyes and the mother has blonde hair and blue eyes?
The baby could have a variety of hair and eye colors, as it depends on the combination of genes inherited from the parents. Possibilities include blonde hair with blue eyes, strawberry blonde hair with brown eyes, or a mix of traits from both parents. Genetic inheritance is complex and not always predictable.
Can to blue eyed parents have brown eyed children?
Yes, it is possible for two blue-eyed parents to have children with brown eyes if both parents are carriers of the brown eye gene. Eye color is determined by multiple genes, so variations can occur in offspring even if both parents have the same eye color.
Is it possible for two parents with brown hair to have an offspring with blonde hair?
If two blonde haired people have a child the child will be blonde as everybody has two hair genes (one from each parent) and you pass one of your genes to your child, to be blonde you have to have two blonde haired genes and as you can only pass blonde genes to your child they will certainly be blonde.Source(s):GCSE science lessons Hi I am sorry to rain on your party but i believe you are incorrect. The reason why is because you can carry a trait but if you are an owner of trait then you have that trait plus others. For example my aunt has blonde hair and her hubby has blonde hair that went to dirty blonde to brown naturally. However, they have a red-head. How is this possible? Doesn't heredity have rules? I am so confussed.
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.
Can 2 people with hazel eyes brown hair have a blonde hair blue eyed baby?
Yes, as eye color includes family history too, though your method may work coincidentally or instead of what I said! Yes they can.. Both my parents have black hair and dark brown eyes.. and i have light blonde hair and blue eyes..!! I mean... yes. My parents have green eyes, and blonde hair, yet I have DARK, DARK brown hair and grey eyes! Pretty sure, my mum has red hair with brown eyes, dad green eyes with brown hair. I however have blonde hair and grey eyes!! And my siblings all vary too. My parents have brown eyes and black hair while I have green eyes and blonde hair, although I have eight siblings all with black hair and brown eyes so it's not really common.
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.
