Speciation Genetics: Reinforcement by Shades and Hues
نویسنده
چکیده
Mating with a member of another species can seriously reduce an organism's fitness, so mechanisms ought to evolve to prevent it where hybridizing species meet. This old idea of 'reinforcement' has found new support in an elegant pair of studies of the ecological genetics of flower colour in an annual herb.

The Genetics of Speciation by Reinforcement
Reinforcement occurs when natural selection strengthens behavioral discrimination to prevent costly interspecies matings, such as when matings produce sterile hybrids. This evolutionary process can complete speciation, thereby providing a direct link between Darwin's theory of natural selection and the origin of new species. Here, by examining a case of speciation by reinforcement in Drosophila...
متن کاملSpeciation by reinforcement: a model derived from studies of Drosophila.
Reinforcement is an increase in premating reproductive isolation between taxa resulting from selection against hybrids. We present a model of reinforcement with a novel type of selection on female mating behavior. Previous models of reinforcement have focused on the divergence of female mating preferences between nascent species. We suggest that an increase in the level of female mating discrim...
متن کاملUnidirectional CI and the consequences of Wolbachia for gene flow and reinforcement
The intracellular bacterial parasites of the genus Wolbachia are widespread among arthropod species. In many hosts, they induce a reproductive incompatibility between uninfected females and infected males. The potential role of this cytoplasmic incompatibility in speciation processes of the bacteria’s hosts has long been debated. In this thesis, we analyze common criticisms of such a role by me...
متن کاملColorimetric properties of wool dyed with Cochineal: Effect of Dye-bath PH
In the present work an evaluation was carried out on the effect dye-bath pH and mordant type on the obtained shades and fastness properties in wool dyeing with cochineal. In this way wool samples were first mordanted with four different mordants and subsequently dyed with cochineal at different levels of dye-bath pH. Colorimetric evaluations were carried out and fastness properties of the dyed ...
متن کاملTheory and speciation.
The study of speciation has become one of the most active areas of evolutionary biology, and substantial progress has been made in documenting and understanding phenomena ranging from sympatric speciation and reinforcement to the evolutionary genetics of postzygotic isolation. This progress has been driven largely by empirical results, and most useful theoretical work has concentrated on making...
