Approximately a third of all the possible crosses … See more The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation. They prevent members of different species from producing See more Pre-zygotic isolation mechanisms are the most economic in terms of the natural selection of a population, as resources are not wasted on the … See more In general, the barriers that separate species do not consist of just one mechanism.
