Abstract

In order to cytogenetically describe the new bovid species saola (Pseudoryx nghetinhensis), comparative G- and Q-banding of saola and cattle (Bos taurus) chromosomes as well as FISH-mapping of 32 type-I markers (29 Texas markers and three additional markers) on saola chromosomes were performed. Saola was shown to have a diploid number of 2n = 50 chromosomes possessing five biarmed autosomal pairs and an acrocentric X chromosome. Homology of saola and cattle chromosomes was indicated by banding patterns and by marker hybridization suggesting that all five biarmed pairs in saola originate from centric fusions involving ten cattle autosomes. However, small intrachromosomal rearrangements cannot be excluded. In this study the first preliminary homology map of these two species is presented.
