Are curls hereditary?
Selection explains why different hair types exist at all, but for any given person, inheritance studies suggest that curly hair mostly follows the rules of Mendelian genetics. Curly hair is dominant, so someone is more likely to have curly or wavy hair if at least one of their parents does.

Individuals who are heterozygous, with one of each allele have wavy hair, which is a blend of the expressions of the curly and straight hair alleles. Blood Typing/ Multiple Alleles. A number of human traits are the result of more than 2 types of alleles …
