Genetic linkage map of the zebra finch genome


The Zebra finch is a model species in evolutionary biology and neurobiology. A limitation to identifying genes underlying variation in traits has been a lack of genomic resources in this species. To help address this problem and complement the zebra finch genome sequence we developed a first generation linkage map for the zebra finch using SNPs. The linkage map provided much insight into the evolution of avian genomes. Click here to read more

Patterns of linkage disequilibrium and recombination across the zebra finch genome


The pattern of linkage disequilibrium across the genome provides valuable insight into the distribution of recombination events, and also has important implications for gene mapping studies. Using the genetic linkage map and the recently completed whole genome sequence I analysed the genome-wide pattern of linkage disequilibrium (LD) and recombination rate in the zebra finch. The analysis revealed unusual patterns of LD and interesting differences between the macro- and microchromosomes. Click here to read more
