Responding to one of Carolyn's comments, I have also seen red-fruited plants show up in the F2 and later generations of Sungold. This means that one of the parents is a red tomato and the other is an orange tomato with the dominant B gene for orange color. See the link below from Frogsleap Farm for information on the genetics of tomato color.

No, it doesn't mean that one of the parents ( complete genome) is a red tomato, S . Pimpinellifoium has been used in the breeding of many cherry tomatoes since pimp has a geneS) for the flat truss type that is typical for so many cherries.
So in breeding Sungold F1, for sure they are breeding in just the gene(s)( associated with the flat truss) but also some associated pigment gene(s) that wentalong for the ride.
And Travis spoke topimp in an earlier post here as well.
So no, S pimp was never one parent with the complete genome being involved.
