Abstract
To further our knowledge on the speciation mechanisms in Spalax ehrenb ergi superspecies, we set out to study the spermatogenesis of hybrid i ndividuals belonging to two different hybrid zones (the one between th e chromosomal species with 2n = 52 and 2n = 58 and the other between t he chromosomal species with 2n = 58 and 2n = 60). The data show an imp aired gametogenesis process for all the hybrids studied, even though t he production of sperm is not completely affected.
