The Unit of Selection in DROSOPHILA MERCATORUM. II. Genetic Revolution and the Origin of Coadapted Genomes in Parthenogenetic Strains.


Drosophila mercatorum is a sexual species that can reproduce parthenogenetically. Previous studies revealed that parthenogenetic strains had "coadapted genomes" with high fitness under parthenogenesis and total homozygosity due to nonadditive and nonmultiplicative fitness interactions between chromosomal segments scattered throughout the genome. To study… (More)
