Is teeth and curly hair a recessive trait or dominate trait plz explain

Since curly hair is a dominant gene, there is a good likelihood that one or two curly-haired parents will produce a curly-haired cutie. 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.

Hope this helped you
