Recently a report on the reindeer chromosomes was published 1965). The chromosome complement was described as consisting of 70 autosomes and a sex chromosome set of the XY-type. All autosomes were acrocentric except one pair which was submetacentric. The X was found to be submetacentric and also the largest chromosome of the complement. The Y was characterized as being the smallest acrocentric chromosome, and the authors stated that the Y chromosome could only occasionally be distinguished from the autosomes by its shorter length. In our studies of the same species we have found a quite different appearance concerning the Y chromosome.
最近发表了一篇关于驯鹿染色体的报告（1965年）。染色体组被描述为由70条常染色体和XY型性染色体组组成。除了一对亚中着丝粒染色体外，所有常染色体都是近端着丝粒染色体。发现X染色体是亚中着丝粒染色体，也是染色体组中最大的染色体。Y染色体被确定为最小的近端着丝粒染色体，作者指出Y染色体仅偶尔因其较短的长度而能与常染色体区分开来。在我们对同一物种的研究中，我们发现Y染色体的外观截然不同。
