Answer:
3/16
Explanation:
Two true-breeding stocks of pea plants are crossed. One parent has red RR, axial flowers AA and the other has white rr, terminal flowers aa
Parent cross RRAA x rraa
Gamete: RA x ra
F1 gen. RrAa
Selfing of F1. RrAa x RrAa
F2 offspring
Rr x Rr Aa x Aa
RR Rr rr AA Aa aa
3/4 red 1/4 white 3/4 axial 1/4terminal
Probability of plants with white axial flowers is 1/4*3/4 = 3/16
I know 1 of them is Nature
