DNA fingerprinting in Speke's gazelle: a test for genetic distinctness, and the correlation between relatedness and similarity.

abstract：:Understanding the contribution of different molecular processes to evolution and development is crucial for identifying the mechanisms of adaptation. Here, we used RNA-seq data to test the importance of alternative splicing and differential gene expression in a case of parallel adaptive evolution, the replicated postg...
