Dan, the colors we observed in the F2 seemed to have a strong dependency on the width of the cross - and we actually seemed to use a red parent less frequently (early on, anyway), than more "recessive" colors. There was also, of course, a dependency on how big a population of F2 we ended up with when pooling results from all of our volunteers on a given cross.
I would have to go back to the individual threads or spreadsheets - but the families that involved a red parent were
Bashful (one parent was found to be crossed)
Brawny
Doc (one parent was found to be crossed)
Eventful (using a red F2)
Grumpy
Plentiful (though it was a red F2, so lots of diversity)
Ruggy
Ruby
Sleepy
Sneaky (though the parent was early generation and hence not stable)
Softy
Teary
Witty
So only 8 of our many, many crosses used a "pure" red parent. Some of those didn't get a lot of work/interest.
Maybe the best indicators are Sleepy and Witty - and we did see lots of color variation even in the F2. You can look at the various F2 threads for those above if you wish to delve deeper.
