Biological species concepy - Answer-Biological species concept (BSC) defines a species as a reproductive community and is thus based on interbreeding as a criterion. "Groups of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups. The BSC has dominated biology since 1940s. Problems with the BSC - Answer-Plants are problematic because of interspecific hybridization between clearly different species; doesnt apply to asexual orgnai...
