Isolation of genes responsible for the morphological evolution of male genitalia in Drosophila

Study period:1992 - 0

Research overview:
Male genitalia of many different animal groups manifests a rapid morphological evolution. Sexual selection has been suggested to be the cause for this phenomenon. Seven closely related species of Drosophila melanogaster are morphologically very similar, and male genitalia is the only reliable character for identification. We have been searching for genes responsible for the interspecific differences in male genitalia by using enhancer detector screening and P element mutagenesis.
