Abstract

Morphological analysis of muksun Coregonus muksun of the Khatanga River basin revealed that along with its typical high-density-rakered form, individuals of the low-density-rakered form also live in this region. Analysis of the genetic polymorphism of three marker regions of mitochondrial (ND1 and COI fragments) and nuclear (ITS1) DNA indicates the polyphyletic origin of these forms. The revealed low level of genetic differentiation of muksun and whitefish C. lavaretus, along with the available data on the absence of clear diagnostic species characteristics, suggest that they belong to the same biological species C. lavaretus.

卡丹加河流域两种Muksun Coregonus muksun（Salmonidae）的形态和遗传多样性是了解Muksun与白鲑C. lavaretus亲缘关系的关键

摘要

muksun的形态分析白鲑的哈坦加流域透露，其典型的高密度rakered形式以来，低密度rakered形式的个人也住在这个地区。线粒体（ND1和COI片段）和核（ITS1）DNA的三个标记区域的遗传多态性分析表明，这些形式的多系起源。Muksun和白鱼C. lavaretus的遗传分化水平低，再加上缺乏明确的诊断物种特征的可用数据，表明它们属于同一生物物种C. lavaretus。
