What stands for dominant allele?
Normally a dominant allele is represented by a capital letter. It can be any letter used. Example; Brown hair is dominant and blond is recessive. B represents the dominant allele (brown) and b represents the recessive (blond) in Bb. You can have any combination of two alleles; BB, Bb, or bb. BB would have brown hair, Bb would have brown hair or a mix, and bb would have blond hair. Instead of B we could have used T or any other letter.
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 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.
Are you more likely to have blond hair or brown hair?
You are more likely to have brown hair because the brown hair gene is a dominant gene, and not the blond hair 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.
If red is the dominant hair color but the father has brown hair and the mother has red hair and the hair color of the father is dominant then what color will the hair of their child be?
It's very hard to answer this question as there are no details on what alleles the fathers or mothers DNA contains. The father has to have an allele for red hair for the child to have a chance of having it. Presuming that the father has a brown and red hair allele and the mother has the same it works out like this. Brown + Brown = Brown Brown + Red = Brown (Because it's dominant) Brown + Red (from other parents) = Brown (Because brown is dominant) Red + Red = Red The chances of brown therefore is 3:1 as you cannot be sure on what the child will receive. MORE like 5-1 his here will be blond
Why do most people have brown hair?
It's all in the Genes. The dominant color gene allele for hair is brown.
What what is an example of a recessive allele?
blue eyes blonde hair etc.. brown eyes and brown hair are dominant
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.
Does blond hair turn brown?
brown is a dominant allele in a blond-brown gene, if you have that allele you'll turn out brunette. Some believe that kids will have lighter hair at birth but which will darken as it's exposed to sunlight which stimulates the chemicals needed for pigment (forgot name of said pigment, but see wikipedia, hair color). This is supported mostly because that's what eye color does- exposure to sunlight stimulates production of pigment in the irises.
What does it mean to have brown hair?
Doesnt "mean" anything. If someone has brown hair the dominant Allele between the two parents happened to be brown hair...
Is brown or blond hair more dominate?
Brown is darker,so yeah brown is more dominant.
