X-linked variation in immune response in Drosophila melanogaster.
This study quantifies the effects of naturally occurring X-linked variation on immune response in Drosophila melanogaster to assess associations between immunity genotypes and innate immune response. We constructed a set of 168 X-chromosomal extraction lines, incorporating X chromosomes from a natural population into co-isogenic autosomal backgrounds, and genotyped the lines at 88 SNPs in 20 X-...
متن کاملCharacterization of X-linked recessive lethal mutations affecting embryonic morphogenesis in Drosophila melanogaster.
This study attempted to assay the zygotic contribution of X chromosome genes to the genetic control of embryonic morphogenesis in Drosophila melanogaster. A systematic screen for X-linked genes which affect the morphology of the embryo was undertaken, employing the phenotype of whole mount embryos as the major screening criterion. Of 800 EMS-induced lethal mutations analyzed, only 14% were embr...
متن کاملIsolation and characterization of X-linked mutants of Drosophila melanogaster which are sensitive to mutagens.
Thirteen X-linked mutants have been isolated in Drosophila melanogaster which render male and homozygous female larvae sensitive to the mutagen methyl methanesulfonate. Their characterization and preliminary assignment to functional groups is described. Four of these mutants are alleles of mei-41 (Baker and Carpenter 1972). Like previously isolated alleles of this locus, these mutants reduce fe...
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 کاملVital Genes That Flank Sex-Lethal, an X-Linked Sex-Determining Gene of DROSOPHILA MELANOGASTER.
The X-chromosome:autosome balance in D. melanogaster appears to control both sex determination and dosage compensation through effects on a maternally influenced sex-linked gene called Sex-lethal (Sxl; 1-19.2). To facilitate molecular and genetic analysis of Sxl, we attempted to determine the locations of all ethyl methanesulfonate (EMS)-mutable genes vital to both sexes in the region between 6...
