One type of pea plant has a trait with two variations: The flowers (trait) are either purple or white (variations).
Crossing 2 purple flower plants gave all purple flower plants.
Crossing 2 white flower plants gave all white flower plants.

White because if you cross a purple flowers and white flowers you get all white flowers.
White because if you cross two white flowers you get all white flowers.
Purple because if you cross purple flowers and white flowers you get all purple flowers.
Purple because if you cross two purple flowers you get all purple flowers.
