Wavy Hair Gene
Uncombable hair syndrome caused by mutations in the padi3 tchh or tgm3 gene researchers speculate that the genes associated with these disorders probably also contribute to normal variations in hair texture and thickness although little is known about the roles these genes play in normal hair. However its not always quite so clear cut and depending on the type and strength of the genes you can end up with something in between such as wavy hair.
People with straight hair had two copies of the straight version people with curly hair had two curly versions and people with wavy hair had one of each.
Wavy hair gene. The straight hair in caucasians is likely caused by a mutation in the tchh gene while that in east asians by mutations in the edar and the fgfr2 genes. Human ancestors have curly hairs. Even if 2 parents have wavy coats they can still carry a curl gene and have curly pups in a litter.
As mentioned earlier curly hair is an autosomal dominant trait which means that one of the parents has straight hair while the other has curly hair. Straight hair may provide advantage in cold resistance andor in hair protection by oil secreted from skin glands. The variant may have been selected for in east.
So your case would be pretty easy to explain. If paired to a straight haired person ss then the kids would either have straight ss or wavy hair cs. So you get genes of both types but the dominant curly hair gene trumps the straight hair gene and expresses itself in the offspring ie yourself.
Variations in hair texture from coily to straight to kinky to wavy are caused by evolutionary processes that favored a specific texture according to location climate or any other host of factors. That means if one of your parents gives you a curly haired gene but the other gives you a straight haired gene the stronger curly haired gene wins the day and expresses its trait. A wavy haired person can contribute either a c or an s gene.
Back then there was a gene that came in two versions straight and curly. Goldendoodles can have straight wavy or curly hair depending on what type of curl gene they inherit from each parent. That is probably way more than you wanted to know.
The edar gene codes for ectodysplasin a receptor which is part of a molecular pathway that signals hair precursor cells to begin forming a follicle. There is no single curly hair gene and there is no way to genetically alter the presence of curly hair.
