Sex chromosome polymorphism in Oryzomys longicaudatus philippii (Rodentia, Cricetidae).

M Gallardo N, L A González.   

Abstract

Oryzomys longicaudatus philippii has a diploid number 2N = 56 (N.F. = 70). A polymorphism of X-chromosomes is described and a duplication as causal mechanism is postulated. The degree of chromosomal differences among the 4 karyological forms of O. longicaudatus and between those forms with O. l. philippii, enable us to postulate the level of full species for all of them.
