Predicting phenotypic outcomes from genetic crosses is often very difficult for biology students, especially those with learning disabilities. With our mathematical concept, struggling students in inclusive biology classrooms are now better equipped to solve genetic problems and predict phenotypes, because of improved understanding of dominance and recessiveness. Furthermore, this new concept has gained popularity among our dyslexic biology students who usually have difficulty in conceptualizing alleles and genes with alphabetical letters. In addition to giving these students the option of using numerical representations, this method minimizes confusion that is often caused by alphabetical representations.
