Nucleotide polymorphism at the xanthine dehydrogenase locus in Drosophila pseudoobscura.

Molecular biology and evolution - 1 Jan 1992

Riley M A, Kaplan S R, Veuille M

Abstract excerpt

Sequential polyacrylamide electrophoresis has revealed 20 allozymes of xanthine dehydrogenase (XDH) in Drosophila pseudoobscura. DNA sequence determination of seven isolates of the Xdh locus that represent six allozyme classes are presented here. Of the 5,456 sites examined, 180 are polymorphic, with 27 polymorphisms occurring at nonsynonymous, or replacement, sites. An average of nine amino acids differ between...
