The gene for red hair is recessive, so a personneeds two copies of that gene for it to show up or beexpressed. That means even if both parents carry the gene, just onein four of their children are likely to turn out to be aredhead..
Consequently, can two redheads have a redhead baby?
In order to be a redhead, a baby needstwo copies of the red hair gene (a mutation of theMC1R gene) because it is recessive. This means if neither parent isginger, they both need to carry the gene and pass iton — and even then they will have just a 25% chance ofthe child turning out to be a redhead.
Additionally, are all redheads genetically related? About 1 to 2 percent of the human population has redhair. Redheads have genes to thank for their tresses.Research shows red hair usually results from a mutation in agene called MC1R, which codes for the melanocortin-1receptor.
In this regard, is red hair a sign of inbreeding?
Red hair is caused by a relatively rare recessiveallele (variant of a gene), the expression of which can skipgenerations. It is not likely to disappear at any time in theforeseeable future.
Why is red hair so rare?
Red hair is associated with the gene MC1R, arecessive and somewhat rare gene that occurs in only about 2percent of the world's population, according to the NationalInstitutes of Health. That means both parents must carry a copy ofthe gene to produce a red-haired child and often thetrait skips generations.

That's followed by blonde hair. Red hair,occurring in just 1 to 2 percent of the population, is the leastcommon. Blue eyes are similarly uncommon, and they may be becomingrarer.Which parent determines hair color?
Many other genes also help to regulate thisprocess. Most people have two functioning copies of the MC1R gene,one inherited from each parent. These individuals have blackor brown hair, because of the high amount of eumelanin.

However, other scientists have reported that theinteraction of two genes is responsible for this trait. This traitis reportedly due to a single gene; the presence of frecklesis dominant, the absence of freckles is recessive1.

The laws of genetics state that eye color isinherited as follows: If both parents have blue eyes, thechildren will have blue eyes. The brown eye form ofthe eye color gene (or allele) is dominant, whereas theblue eye allele is recessive.Is brown hair dominant or recessive?
According to one theory, at least two gene pairs controlhuman hair color. One phenotype (brown/blonde) has adominant brown allele and a recessive blond allele. Aperson with a brown allele will have brown hair; aperson with no brown alleles will be blond.Why is my beard Ginger?

The redhead gene is recessive and can skipseveral generations. The gene for red hair is recessive, so aperson needs two copies of that gene for it to show up or beexpressed.

Contrary to what many people assume, redheads did notoriginate in Scandinavia, Scotland or Ireland, but incentral Asia. Their coloring is due to a mutation in the MC1R genethat fails to produce sun-protective, skin-darkening eumelanin andinstead causes pale skin, freckles and redhair.Do redheads feel pain differently?
In our hands, redheads are less sensitive topain and more sensitive to pain inhibition fromanalgesic drugs. But sensitivity to anesthesia [which numbs thesenses] and sensitivity to analgesia [painkillers] are completelydifferent things. They have nothing to do with eachother.Are redheads more prone to anemia?
Having two copies of this gene triggers the productionof high levels of the red pigment phaeomelanin and reduced levelsof the dark pigment eumelanin, resulting in the classic fair skin,freckles, light-coloured eyes and red hair.
