To have blond hair do both of your genes have to be for blond hair?

not necessarily.ok there are two parents each giving the child one gene. if one gene is recessive and one is dominant the dominant gene will decide the hair color. example the recessive gene is black hair and the dominant gene is blonde the child will most likely have blonde hair because the dominant gene is blonde hair. the dominant gene masks the recessive gene

Dark hair parents light hair child how is this possible?
Everyone has at least two genes for hair color, but brown is dominant. If both parents have Brown-Blond genes, then they will have brown hair (because it is dominant over blond), but the child could get one blond gene from each parent and thus be Blond-Blond, and thus be blond.
Are genes expressed all the time?
No you may have a recessive gene being covered up by a dominant gene say you have brown hair your kids may have blond hair if your ancestors passed along blond and brown hair.
How can an offspring show a trait that is not displayed in either of the parents?
dominant and recessive genes say the mom had black hair and her mom had blond hair and the dad had black hair and his mom had red hair if the baby had red or blond hair the parents had those as recessive genes its all about ancestry and genes. PS I'm an 11 year old middle scholar
If someone has a dominant trait such as brown hair and his or her mate has a recessive trait that is brown hair can the offspring have brown hair?
I think you've mis-asked this question, since you've used "brown hair" in both portions of the question. If you mean, if one person has brown hair and another has blond hair, will their children have blond or brown hair? The answer is it's highly likely that the children will have brown hair - brown hair is a dominant gene - but there is a possibility that the child will have blond hair, since the way the genes combine is not always the same. If it were always predictable, all children from the same parents would be the same, like clones of each other; and they're not.
What colour eyes will my child have if one parent has blond hair and blue eyes and one parent has green eyes and blond hair?
There are dominant and recessive genes- according to popular theory, a brown/blond pair of alleles will have a dominant brown allele, but a recessive blond allele- dominant meaning: a person with a brown/blond allele or brown/brown allele will turn out brown, a person with blond/blond allele will turn out blond.Since both parents in this case are blond, they'd technically have a blond child as there is no dominant gene interfering. BUT if they were both brunettes, they could still have a blond child.Red hair is different- see "Genetics" at http://en.wikipedia.org/wiki/Hair_color Depending on the genetics of the mother and father themselves, the child will either have blue eyes if the green-eyed parent has a blue-eyed parent (probably, not 100% of course) and green eyes if the green-eyed parent has 100% green genes so to speak. See: http://www.athro.com/evo/inherit.htmlEye colour is not fully mapped out so it's more a game of probabilities.

What is genotypephenotype?
Genotype is the genes you have inherited for a certain condition (say you have two recessive genes for cystic fibrosis) and phenotype is the result of genotype and environmental factors added together (you will develop cystic fibrosis). ---- Penotype is the actual genes that you inherit from your parents. Phenotype is the genes that are actually expressed in your body. For instance, you may inherit genes for both red hair and blond hair from your parents, but you will only have one hair color. Both redhead and blond genes are part of your genotype, but only the genes for the hair color you actually have are part of your phenotype.
What is a dominant genes?
A dominant gene or variant, refers to gene alleles ("variants") that "beat" other (recessive) genes. Meaning that if an individual has both a dominant and a recessive allele for a certain trait, the dominant allele will express itself "over" the recessive one, affecting the phenotype accordingly. A common example, while being a simplification of the actual complexities of the matter, is hair color. Brown hair is dominant over blond hair. A person with blond hair has both genes for that trait recessive, while a person with brown hair can have either both "brown hair color" genes or one "brown hair color" gene plus one "blond hair color" gene.
Can a blond hair mom and a dark hair father produce a blond hair child?
Yes, however it is much rarer as dark genes are dominant. My father had dark hair and my mother had blonde hair - I have dark hair.
If both parents have blond hair and blue eyes will ther baby have the same?
Each person have 2 genes for almost all characters we own. Blond hair and blue eyes are traits that are determined genetically by recessive gene variants. Such genes can express only in the absence of the dominant genes (in this case the genes for black/red hair or dark/green eyes). The dominant gene always suppresses the recessive ones. So If both parents have blond hair and blue eye, thus none of them posses dominant genes, it means that their offspring cannot show a dominant character, and yes he/she will also have blond hair and probably blue eyes. Probably blue, as for eyes the grey color is more recessive then blue, and parents might carry its gene as well.
Can kids be born with different color of hair then both parents have?
Obviously if a child has pink or blue hair, that doesn't mean that either parent also had pink or blue hair. There are several genes involved with hair color which can allow varying shades of colors. Also, hair color may change with age, especially blonds darkening. Like many genes, there are both dominant and recessive genes with hair color. Red hair and blond hair are both recessive genes (at least in their most common form). So, two parents could be carriers of the red hair gene, but only their child receives both genes and has red hair. However, if the two parents have red hair, then the child should also have red hair. Likewise, parents with brown hair can have a blond child, but two blonds wouldn't have a black haired child. There may be more subtle issues causing an apparent mixing of hair shades.
Why do most dutch people have blond hair?
Native Dutch have blond hair because they have genes responsible for blond hair. Two blonds have a high change making blond haired kids. A blond an a dark haired person usually make non-blond childeren. Genes responsible for blond hair are also found in other west and nordic civilizations (Germany, Denmark, Sweden, Norway, Finland, Iceland, Scotland, Ireland, England). You might say most germanic speaking countries tend to have most blonds and light eyes.
Why are Japanese people born with black hair?
The same reason that white people are born with brown blond or red hair...genes...
Are genes expressed all the time?
No you may have a recessive gene being covered up by a dominant gene say you have brown hair your kids may have blond hair if your ancestors passed along blond and brown hair.
What do the kids look like?
blond hair in both
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.
Do you have to be blond?
No you do not have to be blond you will usually be blond by your families genes or you might of colored it that way .
