, including sailfin mollies, Poecilia latipinna (table 1). Microsatellite markers, however, combine the advantage of high variability with nuclear codominant inheritance and are thus most suitable for parentage analyses (Queller et al., 1993 ). Consequently, they have almost entirely replaced earlier

In both cases the preference predates the occurrence of the trait, lending strong support to the pre

Introduction Predation risk can affect time spent searching for mates, evaluating and courting potential mates, and copulating (Magnhagen, 1991; Sih, 1994). As such, there

Poecilia formosa uses sperm of Poecilia latipinna or P. mexicana for its gynogenetic reproduction. Normally, P. formosa lives in sympatry with only one of these species. Near Tampico, Mexico, one population of P. formosa is living in sympatry with both sperm-donor species. In the present study, using

(Basolo, 1996). The sword is only one of a variety of sexually dimorphic fin elaborations in poeciliid fishes. Male sailfin mollies, Poecilia latipinna , possess a large dorsal fin (sailfin) and perform an elaborate courtship display (Farr et al., 1986; Ptacek & Travis, 1996). Females prefer to associate
