The Cantabrian brown bear (Ursus arctos) is a highly endangered species in Spain and basic studies are necessary in order to bank its germplasm. Sperm heads are mainly made up of chromatin, thus their shape depends partly on chromatin structure. Thawed semen from 10 bears was used to analyze chromat...
