Answer:
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 )
