A gene that takes time to come into effect such as puberty hormones and greying hair.
Each and every person has the same set of genes - about 20,000 in all. The differences between people come from slight variations in these genes. For example, a person with red hair doesn't have the "red hair gene" while a person with brown hair has the "brown hair gene." Instead, all people have genes for hair color, and different versions of these genes dictate whether someone will be a redhead or a brunette.
Because people look pretty with fat noses.
You are more likely to have brown hair because the brown hair gene is a dominant gene, and not the blond hair gene.
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
Yes, of course they can. The redhead gene (or any other gene for that matter) can skip generations. Two people with naturally blonde hair can have a child with brown hair, you cant say what colour hair a child will have just based on what colour it's parents hair is alone.
It's all in the Genes. The dominant color gene allele for hair is brown.
The gene that determines a man's hair is on the x chromosome.
curly hair, as the dominant gene overrules the recessive gene I THINK :)
Red hair is rare because the trait is a recessive gene when paired up with other types of hair. In most cases both sides of the parents have to have that gene to even make it possible. Many people have the trait for red hair, but it takes 2 people with the trait to produce an offspring with red hair, making it twice as difficult. That is why red hair is not typical.
People sell their hair.
