One species of Drosophila in particular, D. Sexual penetration The terms "fruit fly" and " Drosophila " are often used synonymously with D.Abstract Forms of reproductive isolation that act after copulation but before fertilization are potentially important components of speciation, but are studied only infrequently. We examined postmating, prezygotic reproductive isolation in three hybridizations within the Drosophila simulans species complex. The testes of Drosophila melanogaster provide an important model for the study of stem cell maintenance and differentiation, meiosis, and soma-germline interactions. Testes are typically isolated from adult males days after eclosion from the pupal case.

The concept of gametic isolation has its origins in the edition of T. Involving either positive assortative fertilization as opposed to self-incompatibility or negative assortative fertilization, it occurs after mating but prior to fertilization.

The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation. They prevent members of different species from producing offspring , or ensure that any offspring are sterile. These barriers maintain the integrity of a species by reducing gene flow between related species. The mechanisms of reproductive isolation have been classified in a number of ways. Zoologist Ernst Mayr classified the mechanisms of reproductive isolation in two broad categories:
