The Giemsa-banding patterns of chromosomes from the arctic fox (Alopex lagopus), the red fox (Vulpes vulpes), the kit fox (Vulpes macrotis), and the raccoon dog (Nyctereutes procyonoides) are compared. Despite their traditional placement in different genera, the arctic fox and the kit fox have an identical chromosome morphology and G-banding pattern. The red fox has extensive chromosome arm homoeology with these two species, but has only two entire chromosomes in common. All three species share some chromosomes with the raccoon dog, as does the high diploid-numbered grey wolf (Canis lupus, 2n = 78). Moreover, some chromosomes of the raccoon dog show partial or complete homoeology with metacentric feline chromosomes which suggests that these are primitive canid chromosomes. We present the history of chromosomal rearrangements within the Canidae family based on the assumption that a metacentric-dominated karyotype is primitive for the group.
对北极狐（Alopex lagopus）、赤狐（Vulpes vulpes）、敏狐（Vulpes macrotis）和貉（Nyctereutes procyonoides）的染色体吉姆萨带型进行了比较。尽管北极狐和敏狐传统上被置于不同的属中，但它们具有相同的染色体形态和G带型。赤狐与这两个物种有广泛的染色体臂同源性，但只有两条完整的染色体相同。这三个物种都与貉共享一些染色体，高染色体数目的灰狼（Canis lupus，2n = 78）也是如此。此外，貉的一些染色体与中着丝粒猫科染色体表现出部分或完全同源性，这表明这些是原始犬科染色体。基于中着丝粒主导的核型是该类群原始核型的假设，我们展示了犬科家族内染色体重排的历史。
