Table 1 Descriptive parameters for genetic diversity, neutrality tests and divergence. Results are shown for each gene in D. mojavensis and D. arizonae. In the case of D. mojavensis, genetic diversity and divergence values correspond to the average across the four populations (See Methods for abbreviations)

From: Positive selection at sites of chemosensory genes is associated with the recent divergence and local ecological adaptation in cactophilic Drosophila
