| genomic variation in cline shape across a hybrid zone. | hybrid zones are unique biological interfaces that reveal both population level and species level evolutionary processes. a genome-scale approach to assess gene flow across hybrid zones is vital, and now possible. in mexican towhees (genus pipilo), several morphological hybrid gradients exist. we completed a genome survey across one such gradient (9 populations, 140 birds) using mitochondrial dna, 28 isozyme, and 377 aflp markers. to assess variation in introgression among loci, cline parameters ... | 2012 | 23170209 |
