Transgressive segregation, adaptation and speciation
@article{Rieseberg1999TransgressiveSA, title={Transgressive segregation, adaptation and speciation}, author={L. Rieseberg and M. A. Archer and R. Wayne}, journal={Heredity}, year={1999}, volume={83}, pages={363-372} }
The production of extreme or ‘transgressive’ phenotypes in segregating hybrid populations has been speculated to contribute to niche divergence of hybrid lineages. Here, we assess the frequency of transgressive segregation in hybrid populations, describe its genetic basis and discuss the factors that best predict its occurrence. From a survey of 171 studies that report phenotypic variation in segregating hybrid populations, we show that transgression is the rule rather than the exception. In… CONTINUE READING
