Assertion is true, but Reason is false.
Reason can be corrected as
Reproductive isolation prevents members of one species to mate and produce offspring with another species.
Thus, it prevents the bringing of distinctive morphological characters.
Species are groups of potentially interbreeding natural populations that are isolated (rather than being reproductively isolated) from other such groups.
