At at least some of the offspring will get an/the all red combo right?
In principle, this is correct. Problem is you don't know how many alleles
need to be in the proper combination. The fraction of offspring that get
the proper combination could be anywhere from 100% to 1 in millions (or
fewer). I have no information on the number of redVFT offspring that will
also be red.
Hope this clarified my last post.
