[Detailed analysis of a new translocation in a domestic pig]

A sterile minisibs (mini Siberian swine) boar with normal sexual behaviour was studied by the routine, C- and high resolution G-banding chromosome techniques. A new reciprocal translocation was identified involving chromosomes 12 and 13. The numbers of diakinesis and sperms were very low. The synaptonemal complex was typical of reciprocal translocations.
