In order to aid comparison of estimates of genetic parameters between dominant and codominant makers for population genetics society, we developed a genetic dominance simulation program to determine how the dominance and biallelism could affect the estimation of population genetic statistics. The simulation indicates that genetic diversities within populations based on allozyme allele frequencies that were transformed into biallelic dominant data were significantly lower than for nontransformed multiallelic codominant data, while population differentiation was biased upwardly in each experimental species. Microsoft Active Server Pages (ASP) is combined with Active Data Objects (ADO) to create a dynamic web site for the distribution of the simulation program. The user's information is required to be registered into a database and they can also register their published papers to be shared with genetics community.Keywords: Genetic dominance simulation, Active Server Pages, Active Data Object
