Is Wavy Hair Dominant Or Recessive In the case of wavy hair if an individual inherits the W gene from either their mother or father they will have wavy hair This means that even if the other parent carries a recessive gene for straight hair the dominant W gene will mask its effect resulting in wavy hair
Genetic factors appear to play a major role in determining hair texture straight wavy or curly and the thickness of individual strands of hair Studies suggest that different genes influence hair texture and thickness in people of different ethnic backgrounds There are two versions of the hair type gene curly C and straight s Hair type is an interesting case of something called incomplete dominance What this means is that with hair type if you have one of each version of the gene you get a mix of the two or wavy hair

A 2009 study identified a genetic variant in the TCHH gene that is responsible for 6 of the variance in curly wavy and straight hair However it s essential to understand that the presence or absence of this variant doesn t guarantee straight or curly hair but rather influences the odds 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
