Is Curly Hair A Recessive Gene. The presence of freckles is dominant, the absence of freckles is recessive1. However, a single gene has yet to be found to be solely responsible for the curly (or straight) hair.

If The Letter In Noted As A Capital Is In Dominant And If It Is A Lowercase Letter It Is Recessive.
But genetics are tricky, and there’s a chance that two parents with curls could carry the straight hair recessive gene, and pass that onto their offspring. An allele is the term geneticists use to refer to a version of a gene. Of course, wavy and curly is in the eye of the beholder!
Naturally Curly Hair Is A Dominant Gene, While The Gene For Straight Hair Is Recessive.
A wavy haired person can contribute either a c or an s gene. Two parents with curly hair (a dominant trait) are wondering how likely it will be that their first child would have curly hair. It has been long established that curly hair is a dominant trait in caucasians and straight hair is recessive.
14 Is Curly Hair Dominant Or Recessive?
As already mentioned, curly hair is an autosomal dominant trait, which means that one of the parents has straight hair, while the other has curly hair. Allele, allelomorph.(genetics) either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome and that control the same character. That is because the curly headed parents, cc, can only contribute a c gene and the straight haired parent, only an s gene.
It Is Not True At All.
That means even if both parents carry the gene , just one in four of their children are likely to turn out to be a redhead. Those with a straight hairline have inherited the recessive gene. However, other scientists have reported that the interaction of two genes is responsible for this trait.
But, The Long Hair Gene Is A Recessive Gene, So You Need Both Copies In Order To Get Long Hair.
So, you get genes of both types, but the dominant curly hair gene trumps the straight hair gene and expresses itself in the offspring, i.e., yourself. A geneticist determines that they are both heterozygous for curly hair (meaning they have one dominant and one recessive allele each). Which of these hair traits is a recessive gene?
