Introgressive Hybridization
This book is a collection of the thirteenth series of the Laity Lectures of the New York Academy of Medicine. Delivered for the benefit of those interested in the medical and teaching professions and also in the related fields of social service and public health, the essays have a common theme which emphasizes the interrelationship of medical research with the public and its elected representat...
متن کاملAsymmetric Introgressive Hybridization Among Louisiana Iris Species
In this review, we discuss findings from studies carried out over the past 20+ years that document the occurrence of asymmetric introgressive hybridization in a plant clade. In particular, analyses of natural and experimental hybridization have demonstrated the consistent introgression of genes from Iris fulva into both Iris brevicaulis and Iris hexagona. Furthermore, our analyses have detected...
متن کاملIntrogressive Hybridization in a Natural Population of Tradescantia.
ETAILED analyses of populations containing natural hybrids have D been reported recently. ANDERSON (1936) has suggested a method for expressing quantitatively the extent of hybridity of a population and for comparing various populations, and this method has been applied to various genera such as Tradescantia (ANDERSON 1936) , Solidago (GOODWIN 1937), and Iris (RILEY 1938, 1939) The present pape...
متن کاملIntrogressive Hybridization between Anciently Diverged Lineages of Silene (Caryophyllaceae)
Hybridization has played a major role during the evolution of angiosperms, mediating both gene flow between already distinct species and the formation of new species. Newly formed hybrids between distantly related taxa are often sterile. For this reason, interspecific crosses resulting in fertile hybrids have rarely been described to take place after more than a few million years after divergen...
متن کاملIntrogressive hybridization: brown bears as vectors for polar bear alleles.
The dynamics and consequences of introgression can inform about numerous evolutionary processes. Biologists have therefore long been interested in hybridization. One challenge, however, lies in the identification of nonadmixed genotypes that can serve as a baseline for accurate quantification of admixture. In this issue of Molecular Ecology, Cahill et al. (2015) analyse a genomic data set of 28...
