Describe the different genotype and phenotypes for the white and purple flower example.
What will be an ideal response?
A plant with genotype PP has the phenotype of purple flowers. Because purple colour (P) is dominant to white colour (p), a pea plant with genotype Pp also has the phenotype of purple flowers. This means, white pea plants must have the genotype pp.
