Heterochromatin and G-Banding of the Red Bracket Deer , Mazama americana temama ( Cervoidea , Artiodactyla ) with a Probable Non-Robertsonian Translocation

Few studies have been published of the chromosome structure of animals in the tribe Odocoileini (American deer) despite the great number of species in this group. Of at least 12 species (Morris 1965), only Odocoileus hemionus, O. virginianus (Wurster and Benirschke 1967) and Pudu pudu (Koulischer et al. 1972) have been analyzed in detail. Taylor et al. (1969) mention the finding of 2n=68 in a single specimen of Mazama americana obtained from the Philadelphia Zoo and kindly made this material available to us for inspection. We have recently had the opportunity to study a family of Mazama americana temama with very different results of those described by Taylor et al. (1969). More over, the new banding techniques now available allowed the identification of an unusual nonreciprocal translocation in one member of this family. This com munication describes the findings of these studies.
