Chromosome analyses were carried out on bone marrow cells from three elephant seal pups (Mirounga leonina), a species characterized by a 2n = 34 chromosome number. Arm ratios for the different chromosomes were calculated to facilitate the classification of chromosomes into groups. The karyotype of the southern elephant seal differs from other reported 34-chromosome phocids in the morphology of the Y chromosome and in that of one of the autosomal chromosome pairs.
对三头海象幼崽（南象海豹，Mirounga leonina）的骨髓细胞进行了染色体分析，该物种的染色体数目为2n = 34。计算了不同染色体的臂比，以利于将染色体分类成组。南象海豹的核型在Y染色体和一对常染色体的形态方面与其他已报道的具有34条染色体的海豹科动物不同。
