Altitudinal Variation at Duplicated Î²-Globin Genes in Deer Mice: Effects of Selection, Recombination, and Gene Conversion
On the cover: The deer mouse (Peromyscus maniculatus) has an extremely broad altitudinal distribution, and tandemly duplicated betaglobin genes contribute to adaptive differentiation in blood-oxygen affinity between populations that are native to different elevational zones. Observed patterns of nucleotide diversity and haplotype structure suggest that nonrandom associations between alleles at linked beta-globin genes may be maintained by epistatic selection.
