The answer is A as this is how we discovered alleles and their dominant/recessive nature.

Theoretically if traits were controlled by only 1 gene then every time you bred 2 purple flowers together you would always get offspring that are also purple, but if there were 2 genes and these 2 flowers had recessive white alleles then some offspring would be white.
