In watermelons, the gene for green fruit (G) is dominant to the gene for striped fruit, and the gene for round shape (R) is dominant to the gene for oval shape. Suppose a plant with genotype GGrr, is crossed with a plant with genotype ggRr. What would be the expected phenotypes among the offspring?  
F. 100% green and oval.

G. 50% striped and round; 50% striped and oval.

H. 100 % green and round.
