Molecular population genetics of Xdh and the evolution of base composition in Drosophila.

Genetics - 1 Dec 2002

Begun David J, Whitley Penn

Abstract excerpt

Few loci have been measured for DNA polymorphism and divergence in several species. Here we report such data from the protein-coding region of xanthine dehydrogenase (Xdh) in 22 species of Drosophila. Many of our samples were from closely related species, allowing us to confidently assign substitutions to individual lineages. Surprisingly, Xdh appears to be fixing more A/T mutations than G/C mutations in most...
