Three examples of genetics and evolution simulation concerning Mendelian inheritance, genetic mapping, and natural selection are used to illustrate the use of simulations in modeling scientific/natural processes. First described is the HERED series, which illustrates such phenomena as incomplete dominance, multiple alleles, lethal alleles, linkage, sex-linkage, complementary genes, and epistasis, and simulates the hereditary mechanisms in particular species. A sample printout is used to explain the series. The second simulation discussed is LINKOVER, which involves genetic mapping and retains the essence of planning and performing crosses with living organisms while greatly speeding up the technique. The last simulation described is SELECT, a population genetics program based on simple colored bead models of natural selection in a one locus/two allele situation. It is concluded that, although some problems exist in using such computer simulations in genetics and evolution instruction, students' grasp of many difficult topics can be greatly enhanced through interaction with computer models. Twenty-five references are listed. (LMM)
