So, I had a tomato last year that was supposed to be Ambrosia Red, but it turned out to be a prolific, vigorous, very indeterminate, golf-ball-sized, round, smooth yellow tomato.

Anyway, I saved seeds and grew them this year. The tomatoes it's growing are ribbed like Zapotec, Pink Stuffer, and Yellow Ruffled. I grew all three of those last year, but they weren't that close to this tomato. Anyway, if the ribbed trait is dominant, then my ribbed tomatoes may have cross-pollinated it. If it's recessive, then it already had a parent with a ribbed allele when I planted it last year.

So, I'm wondering is it a dominant or recessive trait to smooth skin?
