Hair Color Genes Dominant Recessive
According to one theory at least two gene pairs control human hair color.
Hair color genes dominant recessive. While sometimes thought of as a color the albino gene is really the absence of color. It is a dominant trait. Thats the reason black is.
Usually darker hair colors are dominant over lighter colors. Blond hair is due to a MISSING gene that makes melanin which makes hair darker. The color is also likely to be darker such as black brown blue tortoise or sable.
It never comes in the chestnut or chinchilla shades. There are no color rings or bands on the hair shaft either. The gene for hair color could be H so blond hair being dominant could have the genetic makeup genotype could be either HH or Hh since one dominant gene will mask a.
The lighter hue g is recessive and produces a light color. This cross would result in. For example if your mom has red hair and your dad has black hair chances are youre going to have black hair because the gene for that color is dominant.
There are two brown alleles B dominant brown and b recessive brown. Sometimes one allele is dominant and it is expressed over the recessive gene. In order to have blonde hair both of your alleles need to be blonde.
The myth is that red hair is determined by a single gene with the allele for red being recessive to. A person with a brown allele will have brown hair. The DNA for blonde or red hair is not as strong as brown.
