The distribution of constitutive heterochromatin (C-banding) in the genomes of nine species of Felidae, one species of Mustelidae, two species of Procyonidae, one species of Viverridae, one species of Canidae, and one species of Ursidae has been studied. In the chromosomes of several felid species the C-band is apparently absent. A few chromosomes show only telomeric staining in one arm or sometimes in both arms. Centromeric and interstitial distribution of heterochromatin has also been demonstrated in other species of Carnivors, but, in general, the C-banded material in felids is comparatively less in amount, and more weakly staining, than in other mammals. Induction of C-banding patterns in certain carnivore species is rather difficult, probably because of the minimal amount of heterochromatin present.
对猫科9个物种、鼬科1个物种、浣熊科2个物种、灵猫科1个物种、犬科1个物种及熊科1个物种的基因组中组成型异染色质（C带）分布进行了研究。在一些猫科物种的染色体中，明显没有C带。少数染色体仅在一条臂上有时在两条臂上显示端粒染色。在其他食肉动物物种中也证实了异染色质的着丝粒和居间分布，但总体而言，猫科动物中C带染色质的数量相对较少，染色也较弱，比其他哺乳动物的情况要弱。在某些食肉动物物种中诱导C带模式相当困难，可能是因为存在的异染色质数量极少。
