Phenotypic variation
differences in visible characters of species i.e darker hair, lighter hair while Genetic variation is differences in DNA and genes (can’t always see)

Genotypic variation
Discontuous variation
A limited number with no intermediates (either you have it or you don’t). This type of variation and is mostly genetic Examples: Blood type, rolling your tongue,
