Two diploid (2N) species of wheat are crossed T.aestivuma (N=23) and T.militinae (N=36), producing mostly infertile hybrid progeny. Rarely one of these progeny is particularly large and also fetrile. If one of these fertile hybrids was crossed back to a T.militinae how many bivalents would you expect to observe in meiosis I within the sterile plants produced by this second cross?
