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 )

it would be rhyolitic hope this

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
