The F1 generation refers to the first filial generation that results from a cross between two parental (P) generations. The characteristics of the F1 generation depend on the traits of the parent plants.
If the question is about a typical Mendelian monohybrid cross where one parent is homozygous for one trait (e.g., purple flowers) and the other parent is homozygous for a contrasting trait (e.g., white flowers), the F1 generation usually exhibits the dominant trait. In this case, if purple is dominant over white, all of the flowers in the F1 generation would be purple.
Thus, if the context of the question relates to a legitimate monohybrid cross with a dominant-recessive relationship, the correct description of the F1 generation would be "All of the flowers are purple."
