Basic Genetics

Same parents but different appearances?

Why are they not identical if they have the same mom and dad?

It all depends on what your parents traits are, depending if they are homozygous dominant or recessive or heterozygous.

Whats homozygous dominant, recessive and heterozygous?

Homozygous is when both alleles are the same.

Dominant is the allele that will show on your outside appearance.

Recessive is the allele that shows your appearance that's in your DNA (doesn't show).

Heterozygous is two different alleles.
