In pole beans, green pods (G) are a dominant trait, while yellow pods (g) are a recessive trait. A bean plant with a GG genotype is crossed with a second plant that has the gg genotype. If this cross produces 500 offspring, approximately how many of the offspring will have green pods?

Why did Gregor Mendel remove the male parts from the flowers of some plants?
To control the crossing between plants
