separate (like purple vs white flowers)

Continuous traits are traits that show a smooth ________ range of variation with many possible values

gradual

Phenotypic Variation is the ___________ in physical traits seen amount individuals in a population

differences (caused by genetic and environmental factors)

Polygenic Traits is the traits that are controlled by _______ genes,
