Is bicolor a single gene trait?
I found some very old seed from an off-type plant that came out as a big red beefsteak back in Ohio, and for three years I have been trying to get a plant to grow and give me a fruit -- a problem for me here in Florida with heat, disease and hurricanes.
Anyway, with some frost protection for a month I just got two little fruits to ripen, and they ripened up as yellow shoulder, red bottom Bicolors. The original seed was probably a labeled bicolor heirloom but I didn't record what it was when I saved the seed.
So assuming the original off-type fruit was a heterozygous F1 red beefsteak, doing a Punnet square on a single trait dominant red gene tells me that what I have is a homozygous recessive F2 plant, and I'm not going to get a big red out of the seed I am fermenting now, correct?
