Explanation:
True breeding for purple and white means that they are homozygous for that phenotype, for example AA is genotype for purple, while aa is genotype for white. Aa is heterozygous and it represents incomplete dominance phenotype. If we cross true breeding for purple and white:
P: AA x aa
F1: Aa Aa Aa Aa (all of them are with incomplete dominance color)
F2 (Aa x Aa): AA Aa Aa aa (1/4 1/2 1/4)
