What would the most recessive tomato be like (only considering traits currently found in domestic tomatoes available for sale)?

Not sure if I understand the question correctly but I assume you mean some kind of mega combination of all known recessive genes in one plant?

A very very small plant that is just alive (because it is so sick) and that only bears one huge yellowish-orange-green tomato?

It would be a potato-leaved micro (2 pairs of dwarf genes), not red or pink, and since good flavor is so elusive, it would taste GREAT. It would be disease resistant, (at least some of those disease resistances are recessive). It would be large, since cherry is dominant. Not round, since round is dominant, but I'm not sure what shape is most recessive. Not sure what color is most recessive, either.

Don't laugh.

That closely describes the weirdest plant that I've ever grown. Not very, very small (about 18"), just alive and sickly from the start, one flower, (it looked like a determinate plant that terminated with no other flowers), one fruit (large but not huge) blocky and lumpy, plant died just before fruit started ripening, fruit color eventually was yellowish-orange-green (striped). It came from a pack labeled NOT Aunt Ruby's German Green, I think, as the writing was small and just about the worst penmanship that I've ever seen (and I've seen a lot, MMMM participants ). Somewhere around here, I still may have the saved seeds of "Determinator" and the original seed pack.

Blocky I've seen once. But lumpy? Rare genes!

Just for color alone, how many recessives?
y - clear skin
r - yellow flesh
gf - green flesh
t - tangerine
og - pigment intensifier (same locus as Beta) and there is your yellowish green-when-ripe
what about stripes? IDK about them.

Carrot leaf is also recessive as is the bright lime green foliage... so maybe a carrot leaf potato leaf (not sure how this would look) with bright lime green variegated foliage white good tasting heart micro dwarf....

shouldn't it be r = non yellow flesh? Red is dominant over pink, no?

Yeah, annoyingly they use capital R for the dominant red, and little r for the recessive yellow. I always think yellow when I see "y"
The only real use for the "official" names is if you want to do a search about it for some reason. I think I've written y for yellow in my notes a dozen times.
