Two diploid (2N) species of wheat are crossed T. aestivuma (N=20) and T. militinae (N=43), producing mostly infertile hybrid progeny. Rarely one of these progeny is particularly large and also fertile. 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?
