Cytotypes of Kirk's Dik-Dik (Madoqua kirkii, Bovidae) Show Multiple Tandem Fusions
Result description
Madoqua kirkii,a miniature African antelope, is noted for extensive chromosomal variation that has been categorized in four distinct cytotypes (A-D). In this investigation, we analyzed the A cytotype (2n = 46, FN = 48) using a suite of molecular cytogenetic approaches. that entailed (i) whole chromosome and subchromosomal painting by FISH, (ii) the study of Madoqua centromeric-specific DNA and (iii) DNA from the junctions of tandemly fused chromosomes. These data, and those of hybrid specimens (A x B cytotypes) in conjunction with published information permitted an interpretation of the probable sequence of chromosomal rearrangements among the M. kirkii cytotypes. We discuss the findings in the context of chromosomal evolution in these antelopes, and the implications that these hold for ex-situ breeding programs of the species.
