| multiple paternity in two natural populations (orchard and vineyard) of drosophila. | male mating success is an important fitness component in drosophila. the seminal fluid conveyed with the sperm inhibits the proclivity of the female to remate and reduces her fitness. nevertheless, females may remate before they have exhausted the sperm from the first male and consequently use sperm from both males. we have studied concurrent multiple paternity (cmp) in two drosophila melanogaster populations, from an apple orchard and a vineyard just after harvest. cmp is high in both populatio ... | 1996 | 8876212 |
| nucleotide variation in the egfr locus of drosophila melanogaster. | the epidermal growth factor receptor is an essential gene with diverse pleiotropic roles in development throughout the animal kingdom. analysis of sequence diversity in 10.9 kb covering the complete coding region and 6.4 kb of potential regulatory regions in a sample of 250 alleles from three populations of drosophila melanogaster suggests that the intensity of different population genetic forces varies along the locus. a total of 238 independent common snps and 20 indel polymorphisms were detec ... | 2004 | 15280235 |
| molecular population genetics of male accessory gland proteins in drosophila. | drosophila seminal proteins have an unusually high rate of molecular sequence evolution, suggesting either a high rate of neutral substitution or rapid adaptive evolution. to further quantify patterns of polymorphism and divergence in genes encoding seminal proteins, also called accessory gland proteins (acp's), we conducted a sequencing survey of 10 acp genes in samples of drosophila melanogaster and d. simulans (acp29ab, acp32cd, acp33a, acp36de, acp53ea, acp62f, acp63f, acp76a, acp95ef, and a ... | 2000 | 11102381 |
| evolutionary inferences from dna variation at the 6-phosphogluconate dehydrogenase locus in natural populations of drosophila: selection and geographic differentiation. | several allozyme-coding genes in drosophila melanogaster show patterns suggesting that polymorphisms at these loci are targets of balancing selection. an important question is whether these genes have similar distributions of underlying dna sequence variation which would indicate similar evolutionary processes occurring in this class of loci. one such locus, 6-phosphogluconate dehydrogenase (pgd), has previously been shown to exhibit clinal variation for fast/slow electromorph variation in the u ... | 1994 | 8138153 |
