What is the phenotype of a plant with the genotype gg?

Answer 1

im assuming that you are using 'G' for dominant gene, and 'g' for recessive gene. since this plant has 2 recessive genes and no dominant genes, it would show the recessive characteristic, whatever that may be

Answer 2

It depends what gg stands for. It is obviously recessive, but unless you know what it stands for, there is no way of knowing.

Answer 3

it is recessive

eg

G = smooth pea

g = wrinkled pea

gg = reccessive, so therefore wrinkled
