Random Chance, Probability

Kit #73
Random Chance, Probability

Students develop a clear understanding of the principles of probability as they relate to genetics using this unique Lab-Aid. Using red and white plastic extrusions and charts to record the experimental data, students learn that: •The result of a single trial of chance event does not necessarily effect the results of later trials of the same event •The chance that two independent events will occur together is the multiplication of their chances of occurring separately Application of this lab activity extends to Mendelian laws of genetics. Students first determined random selection probabilities. They simulate gamete production for the PTC gene. Next, the students simulate a male-female gene pairing during fertilization to produce specific traits. Finally, they establish mathematical genetic formulas.
