Vrijenhoek and Avise will survey mitochondrial DNA (mtDNA)                 variation and phylogeny in unisexual Poeciliopsis fishes and                    their bisexual progenitors in order to capitalize upon the unique               advantages afforded by these atypical genetic systems for                       addressing two questions of broad significance to evolutionary                  biology: (1) is the inheritance of mtDNA strictly maternal?  and                (2) what are the evolutionary longevities and phylogenetic                      relationships of vertebrates that reproduce by asexual or semi-                 sexual means?  The hybridogenetic strains will be studied for                   evidence of paternally-derived mtDNA indicative of occasional,                  low-level "paternal leakage" of mtDNA into zygotes.  Both                       gynogenetic and hybridogenetic Poeciliopsis will be studied in                  terms of mtDNA phylogeny.  By comparing mtDNA variability within                and among the unisexual strains and their sexually-reproducing                  progenitors, the investigators will estimate the ages, clonal                   diversities, and phylogenetic origins of fish in this complex.                  Results should help in addressing long-standing concerns about                  the evolutionary longevities of unisexual taxa, and hence about                 the evolutionary consequences of asexual reproduction.
