Detailed explanation-1: -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-2: -Dominant is always a capital letter and Recessive is always a lower-‐case letter.

Detailed explanation-3: -Curly hair and straight hair are incompletely dominant alleles of one gene. A person with two curly alleles will have very curly hair. A person with two straight alleles will have straight hair. A person with one curly and one straight allele will have wavy hair!

Detailed explanation-4: -A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).
