1. In a certain plant population, yellow seed color is recessive to green seed color. If a yellow seeded plant is crossed with a heterozygote, what is the chance that their offspring will have green seeds?

50%, if you draw out a punnet square crossing Gg with gg your combinations will be Gg, Gg, gg, and gg, and because Green is dominant here, an uppercase G is always green, the only way you can get yellow is two lowercase g’s.
