Explanation: 

Detailed explanation-1: -Mode of Inheritance is the manner in which a genetic trait or disorder is passed from one generation to the next. Autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, multifactorial, and mitochondrial inheritance are examples.

Detailed explanation-2: -Curly hair is considered a “dominant” gene trait. Straight hair is considered “recessive.” To put that in simple terms, that means that if one parent gives you a curly-haired gene and the other parent gives you a straight-haired gene, you’ll be born with curly hair.

Detailed explanation-3: -There is evidence that trichohyalin (TCHH) may affect hair curl in most/all world populations and that other genes such as EDAR and WNT10A only affect specific populations. Hair curl variation in native Africans is very likely a complex trait with multiple genes influencing curl.
