An introductory genetics simulation on the mating of cats selected by color, pattern, and tail presence. Designed to help students understand the processes of scientific reasoning. Covers the basics of single gene traits: dominant, recessive, incomplete, autosomal, and sex-linked. Features genetic ratios, probability, and the importance of sample size as offspring are generated. Builds skills in planning crosses, predicting outcomes, and interpreting experimental results. Students can formulate genetic models, control variables, test, and revise hypotheses. Phenotypes are displayed with actual cat photos. Includes statistical analysis option and student activities.
