Can Tomatoes and Peppers Cross-Pollinate in the Same Pot?

Introduction

Pepper-shaped tomatoes on a plant sharing a pot with peppers raise cross-pollination questions.

Cross-Pollination Doesn't Affect Current Fruit

Even if tomatoes and peppers cross, the effect only appears in seeds planted from that fruit—not the current tomato.

Possible Variety Trait or Physical Deformation

Pepper-shaped tomatoes are likely a variety characteristic or grew against a stem/support.

Conclusion

Cross-pollination between tomatoes and peppers doesn't change current fruit shape.
