A Learning Software Tool on Genetics Statistics

Genetics is complex and challenging due to the requirement of many basic biological concepts. In order to aid in the understanding of the Chi-squared test used in genetics, we have developed a statistical software tool on Mendelian and Xlinked Inheritance using the Java NetBeans IDE. The software tool guides the user through the Chi-squared test for monohybrid, dihybrid and X-linked (sex-linked) crosses to determine the probabilities of inheritance for various traits in an interactive and instructive process. The software tool consists of four primary modules, which include a main (master) module and three worker modules to deal with monohybrid, dihybrid and X-linked crosses. The software was tested in both introductory and advanced biology courses with many positive feedbacks in addition to high scores in many aspects.
