Understanding genetic basis of complex phenotypic traits in wild populations is a considerable challenge given the lessons from humans. Yet, one has to start somewhere. To this end, recent years have seen development genetic linkage maps for few wild bird species such as the Great Reed Warbler and the Collared flycatcher. Siberian jays now join these ranks.
An article describing the first-generation Siberian jay linkage map has now been published on the pages of open access journal BMC Genomics. Apart of the basic stuff and information included into any linkage map, the article features few interesting insights on the organization of Siberian jay genome. It appears that the recombination rate differs considerably between male and female autosomes, and that some degree of recombination and reorganization has occurred between Z-chromosome and autosomes.
The article has been viewed already (in two weeks since publication) over 700 times entitling it for status of a ‘Highly Accessed’ paper (see ranks here).
