犬[Canis familiaris]中期核型由78条染色体组成。所有常染色体均呈远中心或远中心结构，大小逐渐减小。这些特征使得传统的分析方法难以识别同源对。染色体制备来源于至少4个品种的临床正常犬的外周血淋巴细胞的短期培养。犬核型的大多数组成部分很容易区分。在筛选的个体中未检测到显著的g带模式变化。给出了条带模式的一种语法解释。除了条带外，还发现了其他有助于鉴定的特征形态特征。狗狗的稳心X的g带模式与人类的带X非常相似。狗狗的Y是一个微小的稳心，有两个正带。
The canine [Canis familiaris] metaphase karyotype consists of 78 chromosomes. All autosomes exhibit telocentric or acrocentric configurations gradually diminshing in size. These features make identification of homologous pairs by conventional analysis difficult. Chromosome preparations were derived from short-term cultures of peripheral blood lymphocytes obtained from clinically normal dogs representing at least 4 breeds. Most components of the canine karyotype can be distinguished readily. No significant G-banding pattern variations were detected in the individuals screened. An idiogrammatic interpretation of the banding pattern is presented. Apart from bands, other characteristic morphologic features were found which aid in identification. The G-banding pattern of the canine metacentric X is quite similar to that of the banded human X. The canine Y is a minute metacentric having 2 positive bands.
