Genetics of Speciation
The American Genetics Association (AGA) is a nonprofit membership society whose mission is to promote the study of genetics. To meet this obligation, the AGA publishes the Journal of Heredity and promotes research in all fields of genetics. The latter is accomplished through an annual meeting and symposium, as well as by sponsorship of special events, such as workshops and symposia in areas of ...
متن کاملGenetics and ecological speciation.
Species originate frequently by natural selection. A general mechanism by which this occurs is ecological speciation, defined as the evolution of reproductive isolation between populations as a result of ecologically-based divergent natural selection. The alternative mechanism is mutation-order speciation in which populations fix different mutations as they adapt to similar selection pressures....
متن کاملThe evolutionary genetics of speciation.
The last decade has brought renewed interest in the genetics of speciation, yielding a number of new models and empirical results. Defining speciation as 'the origin of reproductive isolation between two taxa', we review recent theoretical studies and relevant data, emphasizing the regular patterns seen among genetic analyses. Finally, we point out some important and tractable questions about s...
متن کاملThe ecological genetics of speciation.
Ecological interactions and the natural selection they cause play a prominent causal role in biological diversification and speciation. As a discipline, ecological genetics integrates the two components of adaptive evolution (natural selection and genetic variability) to study the mechanisms of evolution. Ecological genetics is a fruitful approach to the study of how reproductive isolation can ...
متن کاملSpeciation genetics: current status and evolving approaches.
The view of species as entities subjected to natural selection and amenable to change put forth by Charles Darwin and Alfred Wallace laid the conceptual foundation for understanding speciation. Initially marred by a rudimental understanding of hereditary principles, evolutionists gained appreciation of the mechanistic underpinnings of speciation following the merger of Mendelian genetic princip...
