Answer:

c) purple is the dominant trait

Explanation:

The F1 generation has dominant characteristics because it is the result of the crossing of two homozygous plants (one dominant - AA- and the other recessive- aa). As a result, the F1 generation is heterozygous (Aa) and expresses the dominate characteristic (purple color), however the crossing of F1 generation plants will form both dominant and recessive offspring.
