each letter is it own question

-procedure
a. suppose you are presented with plant a of the species you are studying. it has pink flowers. you want to determine the genotype of the plant.
b. you cross plant a with plant b of the same species. this plant has white flowers and a known genotype of pp.
c. the resulting cross yields six plants with pink flowers and six plants with white flowers. use punnett squares to determine the genotype of plant a.
-analyze and conclude
a. what is the genotype of plant a? explain how you arrived at your answer. what are the possible genotypes and phenotypes of offspring if plant a is crossed with a plant that has a genotype of pp?
b. what ratio of dominant to recessive phenotypes would exist if plant a were crossed with a plant that has a genotype of pp?
c. is plant a the best plant, in terms of genotype, that you can work with to produce as many of the requested seeds as possible? why or why not? which genotype would be best to work with?
