Interspecific hybridization and its consequences
Sign in to track this film in your collection or want list.
Pictures reproductive isolation originating through interspecific hybridization, via amphyploidy (radish-cabbage, new world cottons, goatsbeard species), and by means of introgression (tobacco, rose family, maize-teosinte), and by the direct recombination of the products of crossing and the establishment of recombinations (larkspur). Specifies ways in which natural selection can aid reproductive isolation directly or indirectly. Depicts hybridization as a powerful stimulus in species formation and as a valuable experimental tool for the study of the genetic basis for species differences. Lecture given by Dr. G. L. Stebbins.
