ABSTRACT

Cytogenetic studies were made of pigs in the state of Rio de Janeiro. An intersex pig from the Large White breed with an atypical penis was found among the animals analyzed. On examination it showed a 38,XX/38,XY karyotype (1:2) with testis, epididymis, uterus and vagina. The data suggest a sex chromosome mosaicism.

Keywords: intersex pig; XX; XY; karyotype.
