In a particular plant, green seed color is dominant to blue. If two plants with green seeds were crossed and resulted in 302 green and 98 blue seed plants, what was the most probable genotype of each parent?
A) G × G
B) Gg × Gg
C) GG × Gg
D) gg × Gg

Question

The ratio of green to blue seed plants is close to 3:1, which is typical for a monohybrid cross involving two heterozygous parents (Gg × Gg). This suggests that each parent carries both the dominant (G) and recessive (g) alleles.
