a)

The allele for purple flowers is recessive to the allele for white flowers.

b)

The allele for purple flowers is dominant to the allele for white flowers.

c)

The allele for purple flowers has mutated more times than the allele for white flowers.

d)

The allele for purple flowers is on a different chromosome than the allele for white flowers.
