You have one parent (P1) of the F1 generation. The other parent (P2) is a mystery but can be determined by the results of the offspring, the F1 generation. Given your results in the F1 generation, what were the two most likely genotypes of the P (P1 and P2) generation

P1 = GGBB ( purple stem with green leaves )

P2 = GGyy ( purple stem with yellow leaves )

Explanation:

Determine the two most likely genotypes of the P ( P1 and P2 ) generation

From table :

purple stem with green leaves occurs 90% ( dominant trait )

Green stem with green leaves  occurs 30% ( recessive trait )

let : G = purple stem , g = green stem , B = green leaves, y = yellow leaves

Hence the two most likely genotypes of P1 and P2 are :

P1 = Purple stem with green leaves – GGBB (P-90%, F1-60%) ( from table attached below )

P2 = Purple stem with yellow leaves – GGyy (P-10%, F1-10%) ( from table attached below )
