Abstract

The possible hybrid origin of new species can usually be corroborated by molecular means. Here, we suggest that the segregation patterns of the molecular markers be further analyzed. A true hybrid species should show the patterns under continuous breeding among its members, at least beyond the F2 generation. We applied the guidelines to the putative hybrid species of Sonneratia, a widespread mangrove genus, and concluded that all the observed hybrids in this genus are simple F1's. Thus, S. x gulngai and S. x hainanensis are not true hybrid species. The segregation patterns of molecular markers should be heeded in interpreting the existence of hybrid species.
