✦ Synopsis

The chromosomes of tragelaphine antelopes studied to date are reviewed. All males of the six species of the tribe thus far investigated show the presence of a Y-to-autosome fusion.

It is postulated that the fusion found in the six species had its origin in a common ancestor.

Based on results in present-day species, an interpretation of the possible events in the evolution of the chromosomes of species so far studied is set out.

The hypotheses put forward on the evolution of tragelaphine chromosomes are testable in that banding techniques done on more suitably prepared chromosomes can now examine more critically the re-arrangements identified and postulated in this publication. It is stressed that such banding studies are necessary in members of the tribe to provide further elucidation of the mechanisms of chromosomal evolution in the tribe.
