title: Chromatin condensation patterns of spermatozoa during epididymal passage in a normal and a chimeric bull.
abstract: Cytochemical parameters have been used to investigate the physico-chemical state of chromatin in testicular, epididymal and ejaculated spermatozoa in a subfertile chimeric bull, carrier of a Robertsonian translocation 25/27. The data show a lesser degree of chromatin condensation in comparison with findings obtained in a control fertile bull.
