Banding analysis of the somatic chromosomes of the domestic dog (Canis familiaris)

Abstract

The chromosomes of the domestic dog (Beagle) were investigated by several different staining techniques. G banding, Q banding, and the bis benzimidazol derivative Hoechst 33258, make possible the identification of all 39 chromosome pairs. Constitutive heterochromatin (C bands) was present on a few chromosomes as distinctive, large stained areas; on the other autosomes there was little or no heterochromatin detectable.
