In contrast, if incompatibility were the product of reinforcement (Dobzhansky, 1937; Butlin, 1989; Liou and Price, 1994), it would be expected that selection against hybrids would lead to greater incompatibilities in the sympatric species pair than in the allopatric pair.
However, most sibling species in Recent marine environments are sympatric (Knowlton 1993), suggesting that within-province speciation (either allopatric or sympatric) is relatively common in nearshore marine environments.

These include genetic drift, founder effects, and fixation of alternative advantageous alleles in allopatric populations in response to identical selection pressures (Fisher 1930; Muller 1940; Wright 1940; Mayr 1954).
Sympatric populations of black and white crappie occur to the W of the Coosa River drainage, whereas allopatric populations of black crappie occur to the E of the Coosa River drainage, except where white crappie have been introduced (Lee et al.
