The structure of the Adh locus of Drosophila mettleri: an intermediate in the evolution of the Adh locus in the repleta group of Drosophila.

Abstract

Members of species of the mulleri and hydei subgroups of the repleta group of Drosophila have duplicate Adh genes. The Adh regions of D. mojavensis, D. mulleri, and D. hydei contain three genes--a pseudogene, Adh-2, and Adh-1--arranged 5' to 3'. To understand the evolution of the triplicate Adh structure, we have cloned and sequenced the Adh locus of D… (More)
