Catlab

Judith Kinnear, The University of Sydney, NSW, Australia

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