Contrasting patterns of sequence evolution at the functionally redundant bric à brac paralogs in Drosophila melanogaster.

Abstract excerpt

Genes with overlapping expression and function may gradually diverge despite retaining some common functions. To test whether such genes show distinct patterns of molecular evolution within species, we examined sequence variation at the bric à brac (bab) locus of Drosophila melanogaster. This locus is composed of two anciently duplicated paralogs, bab1 and bab2, which are involved in patterning the adult abdomen,...
