In pea plants, yellow seed color (Y) is dominant and green seed color (y) is recessive. Based on the Punnett squares, what are the chances that the offspring in the second generation will have green seeds? First Generation Y Y

There is a
% chance that the offspring will have green seeds.

-The P generation has yellow and green seeds.

-The F1 generation has all yellow seeds.

-The F2 generation has yellow and green seeds.

Explanation:

Yellow seed color (dominant)  

Green seed color (recessive)  

P generation: In Mendel's experiments the parental generation.  

Yellow seed color

F1 generation: In Mendel's experiments the offspring of the P generation

Yellow seed color and

Green seed color

F2 generation: In Mendel's experiments the offspring of the F1 generation
