I'm guessing your white genetics is a form of r (note that Beta does not work with r, only R.), but that "qualitative" or "bi-color' genes are causing a late addition of lycopene to the development of your tomato, but it's all conjecture on my part.
Darn. I've been puzzling over this trait for some time and keeping an eye out for anything that sounds similar. I hadn't connected it to the bicolor trait, so that's something new for me to think about
