In the datura plant, purple flower color is controlled by a dominant allele p. white flowers are found in plants homozygous for the recessive allele p. a purple-flowered datura plant is self-fertilized, and its offspring are 27 purple-flowered plants and 9 white-flowered plants. if the 27 purple-flowered plants are self-fertilized, how many of the 27 would you expect to segregate both purpled-flowered and white-flowered plants in their offspring?
