Three exon regions of the myoglobin gene of Baikal seal Phoca sibirica have been amplified and sequenced. The sequences have been found identical to those for the myoglobin gene of the North Atlantic seal Halichoerus grypus. Thus, these seal species have separated not earlier than 2.2 billion years before present.
贝加尔环斑海豹(Phoca sibirica)肌红蛋白基因的三个外显子区域已被扩增并测序。这些序列与北大西洋海豹(Halichoerus grypus)肌红蛋白基因的序列相同。因此,这些海豹物种的分化时间不早于距今22亿年前。
