title: Cytogenetical studies of infertile pigs.
abstract: Cytogenetical studies were made on 6 infertile pigs. Post-mortem examination of the reproductive organs of 5 of these pigs showed them to be intersexes. Regardless of the degree of gonadal deviation from the normal, chromosome karyotype of cultured peripheral blood lymphocytes, bone marrow, liver and kidney, revealed that 4 of the intersexes had a 38,XX constitution. One intersex exhibited sex chromosome mosaicism (38XX/38XY) in lymphocytes from the peripheral blood and bone marrow and a normal male karyotype (38XY) in cultured liver and kidney cells. The sixth pig, a phenotypically normal boar, also had a 38XX/38XY chromosome constitution.
