image: Morphologically identical molecular forms of the African malarial vector Anopheles gambiae (M, top; S, bottom) jointly obtain a blood meal. This image relates to two articles that appeared in the Oct. 22, 2010, issue of Science, published by AAAS. One study, by Dr. Mara Lawniczak of Imperial College London in London, UK, and colleagues is titled, "Widespread Divergence Between Incipient Anopheles gambiae Species Revealed by Whole Genome Sequences." The other study, by Daniel Neafsey of the Broad Institute in Cambridge, Mass., and colleagues, is titled, "SNP Genotyping Defines Complex Gene-Flow Boundaries Among African Malaria Vector Mosquitoes." view more
