is dominant two capital letters ex: kk or is dominant two lowercase ex: kk? or even kk..

Dominant is a capital letter and recessive is a lowercase letter. When you have two capital letters together that's called a homozygous dominant, when it's one capital and one lower case it's called heterozygous, and when it's two lower case letters, it's called homozygous recessive.
