A horned goat with testicular hypoplasia was examined cytogenetically. A total of 72 cells were analyzed, 62 of which had an extra X chromosome (2n=61, XXY) and 10 of which had a male karyotype (2n=60, XY). We propose the hypothesis that, in this case, testicular hypoplasia may have been related to mosaicism of the sex chromosomes.
