A candidate species for the study of mutual mate choice is the trinidadian guppy (poecilia reticulata), a species widely used as a model system for the study of sexual selection (reviewed in houde 1997). Guppies (poecilia reticulata) have long been valuable research animals previous research has shown that visual aspects plays a role in mate choice, and has suggested that differences in color specifically has an effect on mate choice.

In 1970s, male guppies (poecilia reticulata) from rivers with high predation pressure were found to have fewer and smaller color spots than those from low predation sites therefore, investigators suggested that male color patterns are the result of balancing selection pressures from female choice for brightly colored males and predation .

This study investigates the role of uv vision in mate choice in a teleost, the guppy (poecilia reticulata peters, 1859) although photons with wavelengths between approximately 400-700 nm excite the sensation of vision in humans ( campbell and dwek, 1984 ), many animals additionally perceive uv wavelengths in the range 300-400 nm ( tovée, 1995 ).

One such species in which males contribute nothing but sperm during mating is the guppy (poecilia reticulata) here, we examined whether female guppies can obtain information on male fertility (ie, direct fertility benefits) via cues used during mate choice. Although male guppies (poecilia reticulata) contribute only sperm to their offspring, preliminary evidence points to male mate choice in this species thus, the hypothesis that male guppies choose their mates was investigated.
Mate choice has an effect on the fitness and mating strategy of a species, and fitness contributes to natural selection and which traits are carried on to future generations in a quest to study the sexual selection of male guppies, poecilia reticulata, we are working with the center for the study of sexual selection in fishes to measure the . In our experiments using the trinidadian guppy ( poecilia reticulata ), this reversal was mediated by mate-copying opportunities, such that a female (the ‘focal’ female) is given the opportunity to choose between two males, followed by a period in which she observes a second female (the ‘model’ female) displaying a preference for the .
