isolating mechanisms The reproductive characteristics which prevent species from fusing. Isolating mechanisms are particularly important in the biological species concept, in which species of sexual organisms are defined by reproductive isolation, i.e. a lack of gene mixture. Two broad kinds of isolating mechanisms between species are typically distinguished, together with a number of sub-types (modified from Mayr 1970):
Gametic isolation is a mechanism of reproductive isolation which inhibits mating between two distinct species, by ensuring that their gametes don’t interact with each other. This incompatibility of gametes prevents the formation of inter-species hybrids, and maintains the integrity of the species.
