- Abstract:
- Extrinsic fitness variation among hybrids is a likely but unproven means by which barriers between highly interfertile species are maintained. In two long-lived Rhododendron hybrid zones, one dominated by F1s, the other by post-F1s, the proportion of parent, Fl and post-Fl genotype classes in the seed rain and the adult population will be determined using existing RAPD markers. Mean viable seed output of each adult class will be calculated, and from this plus the above, mean lifetime fitness will be determined. The difference between fitness of post-Fl hybrids at the two sites, expected to be large, will then be computed to test whether extrinsic selection removes post-F1s from the Fl-dominated site and so maintains species barriers.
