A boar with testicular hypoplasia had 39 chromosomes. Giemsa banded preparations permitted unambiguous identification of an XXY sex chromosome constitution. Spermatogenic tissue was absent as in X chromatin-positive Klinefelter syndrome of man.
一头患有睾丸发育不全的公猪有39条染色体。吉姆萨带型制备技术明确鉴定出其性染色体组成为XXY。如同人类X染色质阳性的克兰费尔特综合征一样，该公猪缺乏生精组织。
