What is the dominant gene for hair?
The Truth About Dominant and Recessive Genes
For hair color, the theory goes: Each parent carries two alleles (gene variants) for hair color. Blonde hair is a recessive gene and brown hair is a dominant gene.
Is hair a dominant or recessive trait?
It has been long established that curly hair is a dominant trait in Caucasians and straight hair is recessive.
Are Your Traits Dominant?
Is curly or straight hair dominant?
Curly hair is considered a “dominant” gene trait. Straight hair is considered “recessive.” To put that in simple terms, that means that if one parent gives you a curly-haired gene and the other parent gives you a straight-haired gene, you'll be born with curly hair.
Is wavy hair dominant?
Curly hair is dominant, so someone is more likely to have curly or wavy hair if at least one of their parents does. Recent research points to trichohyalin, a protein in hair follicles, as having primary influence over hair curl. However, there are many genes contributing to hair curliness, most of them unknown.
Is black hair a dominant trait?
Black hair is the darkest and most common of all human hair colors globally, due to larger populations with this dominant trait. It is a dominant genetic trait, and it is found in people of all backgrounds and ethnicities. It has large amounts of eumelanin and is more dense than other hair colors.
Is straight hair rare?
Hair type and texture are determined by several factors, including genetics. The African hair is more coiled and drier; Asian hair (Korean, Japanese) is straighter and thicker; and Caucasian hair is somewhere in between with around 45% having straight hair, 40% having wavy hair, and 15% having curly hair.
Can two parents with straight hair have a child with curly hair?
It is not possible for two 'unmixed' parents having straight-hair to reproduce an offspring with curly hair. Having said that, two parents, having straight hair or wavy hair, carrying the gene for curly hair which does not express it as a result of incomplete dominance, can reproduce curly-haired offspring.
Do babies get mom or dad's hair?
Mom passes down all (or mostly) straight genes, and dad does the same with his curly genes—your son, therefore, has an even split. Both parents somewhere in the middle – This middle-ground will create the widest variation in your kid's hair type.
Will I go bald if my mom's dad is?
What chance will I or my future offspring be carriers or have the trait? If your mom's dad is bald, then there's a high chance you'll go bald in the future. If your father is bald as well, then those chances go up even more! But even if baldness doesn't run in your mom's family, it's still possible you'll go bald.

Can 2 brunettes have a blonde child?
Brunettes Can Give Birth To Blondes
If one parent is blonde and the other brunette, they might have a blonde child. This can only happen if the brunette parent carries the blonde allele. If he carries only brown alleles, he can only pass on brown alleles, and they'll dominate causing his child to have brown hair.
What is the rarest hair color?
Red Hair. Red hair is the rarest natural hair color. Experts estimate that somewhere between 1-2% of the world's population has red hair.
What is the rarest hair type?

What eye color is dominant?
The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive. Given this information, you can determine what eye colors are dominant in the parents.
Is blonde or black hair dominant?
One explanation is that as dark genes are more dominant, when you compare them to the ones responsible for the lighter colors. Due to this reason, when one parent carries the dominant dark color gene, and the other has the recessive blonde gene, the chances of their children having dark hair is extremely high.
Are blondes rare?
Being naturally blonde is pretty rare.
Only 2 percent of people in the world are natural blondes. (About one in 20 Americans are.) But that doesn't mean it's not popular. One in three women dyes her locks light enough to be considered blonde.
Is dark skin dominant or recessive?
Inheritance of Skin Color
Each gene has two forms: dark skin allele (A, B, and C) and light skin allele (a, b, and c). Neither allele is completely dominant to the other, and heterozygotes exhibit an intermediate phenotype (incomplete dominance).
What race is curly hair from?
The story of human migration and evolution is written in hair DNA. In sub-Saharan Africa, genes favour tight, curly hair.
Is curly hair more rare than straight?
Hair morphology is one of the more conspicuous features of human variation and is particularly diverse among people of European ancestry, for which around 45% of individuals have straight hair, 40% have wavy hair, and 15% have curly hair.
