That oddball plant
 

I have one out of 36 tomato plants that is not true to variety. I planted
(from seed) open pollinated Italians but have one cherry type. Very uniform
golfball-sized with little pointy nipples on them. The plant structure and
leaf characteristics match the Italian plants. I'm wondering if I may have
stumbled onto something new, a la genetics, or did I just get a cherry tomato
seed mixed in?
