Chromosome Conservation in the Bovidae
Abstract
The chromosomes of 12 bovid species were harvested from fibroblast cultures after incorporation of bromodeoxyuridine into early replicating DNA. Q-band karyotypes were constructed, and, when possible, autosomal arms were numbered according to the cattle standard karyotype. Diploid chromosome number ranged from 30 to 60, yet, based on band similarity, chromosome-arm homologies were extensive. Employing the cattle karyotype as the standard, autosomal-arm differences indicative of possible syntenic disruption were noted for only chromosomes 3, 9, and 14. While chromosome-arm homologies were extensive, shared homologous biarmed chromosomes were rare. The commonness of monobrachially homologous biarmed chromosomes among some bovids (e.g., Antilopinae) suggested that reproductive isolation and speciation in some instances might have resulted from centric fusion events.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
