Sex Peptide Causes Mating Costs in Female Drosophila melanogaster
Conflicts between females and males over reproductive decisions are common . In Drosophila, as in many other organisms, there is often a conflict over how often to mate. The mating frequency that maximizes male reproductive success is higher than that which maximizes female reproductive success . In addition, frequent mating reduces female lifespan and reproductive success , a cost that is medi...
متن کاملSex-specific quantitative trait loci affecting longevity in Drosophila melanogaster.
Senescence, the decline in survivorship and fertility with increasing age, is a near-universal property of organisms. Senescence and limited lifespan are thought to arise because weak natural selection late in life allows the accumulation of mutations with deleterious late-age effects that are either neutral (the mutation accumulation hypothesis) or beneficial (the antagonistic pleiotropy hypot...
متن کاملSelective Mating in Drosophila Melanogaster.
LTHOUGH DARWIN (1871) believed that sexual selection was quite dis-A tinct from natural selection, the modern definitions of natural selection (HALDANE 1932; HUXLEY 1938, 1942) include the mating process among the forces of natural selection. DARWIN'S emphasis on the importance of male competition and the preferences of the females in sexual selection has been shown to have been misplaced in mo...
متن کاملContrasting patterns of X-linked and autosomal nucleotide variation in Drosophila melanogaster and Drosophila simulans.
Surveys of molecular variation in Drosophila melanogaster and Drosophila simulans have suggested that diversity outside of Africa is a subset of that within Africa. It has been argued that reduced levels of diversity in non-African populations reflect a population bottleneck, adaptation to temperate climates, or both. Here, I summarize the available single-nucleotide polymorphism data for both ...
متن کاملSex-linked auxotrophic and putative auxotrophic mutants of Drosophila melanogaster.
Thirty-two mutants with improved growth response on a yeast-sucrose compared with a defined medium have been characterized with respect to ribonucleoside supplementability. Twenty mutants respond to either pyrimidine ribonucleoside. Four mutants respond to one or both purine ribonucleosides. Eight mutants ("putative" auxotrophs) do not respond to dietary RNA supplementation. Mapping and complem...
