    The guppy, Poecilia reticulata, is one of the most famous tropical ornamental fish in the world. There are many varieties and breeds which have been bred by aqua lists for many years. The guppy has frequently been used as model organism for experiments in fish genetics because of its short life cycle, ease of breeding and reproductive capacity. The laboratory strains which were created from local (Japanese) strains and varieties were used as an experimental genetic model for aquaculture. These laboratory strains were maintained as closed colonies for five to 20 years in our laboratory. One of the roles of model experiments in fish genetics to perform experiments which take a long time in which are commercially important, such as genetic drift, as the effect of inbreeding during the growth and maintenance of population. In this review, we mainly considered the results obtained in our laboratory relating to genetic drift, and the effects of inbreeding, heterosis and inheritance of quantitative traits.
