• 4:1

• 12:4

• 9:3

• 4:12

Answer 1

12:4

Explanation:

F₁ is the result of a cross between YYRR and yyrr. YyRr is the result of generation. When the F₁ generation self-pollinates, the result is Yellow wrinkled =3 and Yellow round =9. Green round=3 and Green wrinkled= I Thus, a ratio of Yellow and Green will be 12:4.
