Answer: The correct answer would be "the plants have genetic variation for flower color".
Explanation:
Genetic variation, as the name suggests, refers to the variety or differences present at gene or DNA level among different individuals or population.
More the genetic variation more are the traits or phenotype of the characters.
Different in DNA sequences and different combination of alleles or genes lead to increase in genetic variation.
For example,different shape, size, colors, appearance, texture, et cetera.
Similarly, the different flower colors also show the presence of genetic variation in a population.
Different combination of alleles lead to expression of different flower colors such as purple and white.
