Question

A tall, purple-flowered pea plant (ttpp) is allowed to self-pollinate. (the recessive alleles code for short plants and white flowers.) the phenotypic ratio of the resulting offspring is 9:3:3:1. what is the genotype of the plant whose phenotype appeared once out of every 16 offspring (the "1" in the 9:3:3:1 ratio)?

Answer 1

When the phenotype ratio of the resulting offsrping is 9:3:3:1, the genotype of the plant will be ttpp. The genotype of the plant whose phenotype appeared once out of every 16 offspring the "1" in the 9:3:3:1 ratio is ttpp. So the answer in this question is ttpp.
