Cytogenetic Study of a Cercopithecus pogonias grayi × Cercopithecus mona mon a Hybrid

Abstract

The G- and C-banded karyotypes of hybrid born of the cross between a male Cercopithecus pogonias grayi (2 n = 72 XY) and a female C. mona mona (2 n = 68 XX) are reported. The chromosome number is 2 n = 70 and equals half the total number of parental chromosomes. A correlation between the hybrid karyotype and those of its parents is proposed. The typical autosomes of C. pogonia grayi are again found in the young hybrids.
