Absence of protein polymorphism in the Ras genes of Drosophila melanogaster.

Journal of molecular evolution - 1 Nov 1999

Gasperini R, Gibson G

Abstract excerpt

Sequence analysis of 27 alleles of each of the three Ras-related genes in Drosophila melanogaster indicates that they all have low levels of polymorphism but may experience slightly different evolutionary pressures. No amino acid replacement substitutions were indicated in any of the sequences, or in the sibling species D. simulans and D. mauritiana. The Dras1 gene, which is the major ras homologue in Drosophila,...
