Fecundity Decrease in Drosophila simulans in the absence of Wolbachia

Posted Posted in Undergraduate Research

By: Jack Taylor, Biochemistry and Molecular Biology ’15 Sponsor: Michael Turelli, Ph.D. Ecology and Evolution Many species of arthropods host Wolbachia, maternally transmitted bacteria that often influence host reproduction. This manipulation of host reproduction has contributed to Wolbachia becoming a normally-present infection of many Drosophila simulans. The Y36 isofemale line, a population of Drosophila simulans created from a single female collected in 2010 in Yolo County, produces flies which have an unusual phenotype when reciprocally crossed with uninfected simulans populations denoted U. The cross between Y36 male and U female produces female offspring with significantly lower fecundity than the reciprocal cross (Y36 female with U male). It is possible that this effect is a result of a paternal defect gene […]
