Genome-Wide Association Study on Male Genital Shape and Size in Drosophila melanogaster
Male genital morphology of animals with internal fertilization and promiscuous mating systems have been one of the most diverse and rapidly evolving morphological traits. The male genital morphology in general is known to have low phenotypic and genetic variations, but the genetic basis of the male genital variation remains unclear. Drosophila melanogaster and its closely related species are mo...
متن کاملGenome-Wide Association Study of Extreme Longevity in Drosophila melanogaster
Human genome-wide association studies (GWAS) of longevity attempt to identify alleles at different frequencies in the extremely old, relative to a younger control sample. Here, we apply a GWAS approach to "synthetic" populations of Drosophila melanogaster derived from a small number of inbred founders. We used next-generation DNA sequencing to estimate allele and haplotype frequencies in the ol...
متن کاملGenome-Wide Association Analysis of Radiation Resistance in Drosophila melanogaster
BACKGROUND Ionizing radiation is genotoxic to cells. Healthy tissue toxicity in patients and radiation resistance in tumors present common clinical challenges in delivering effective radiation therapies. Radiation response is a complex, polygenic trait with unknown genetic determinants. The Drosophila Genetic Reference Panel (DGRP) provides a model to investigate the genetics of natural variati...
متن کاملMultiple Quantitative Trait Loci Influence the Shape of a Male-Specific Genital Structure in Drosophila melanogaster
The observation that male genitalia diverge more rapidly than other morphological traits during evolution is taxonomically widespread and likely due to some form of sexual selection. One way to elucidate the evolutionary forces acting on these traits is to detail the genetic architecture of variation both within and between species, a program of research that is considerably more tractable in a...
متن کاملMaternal effect influencing male genital disc development in Drosophila melanogaster.
HE development of the testes and associated organs in Drosophiln melanoT g m t m has been studied by many investigators (STERN 1940. 1941a. b; STERN and HADORS 1939; URSPRUNC 1963). A review of the literature has been given by RODI:.NSTIXN (1950). During the larval and early pupal stages. the testes are ellipsoidal in form. Following attachment of the testes to the developing seminal vesicles. ...
