In this Candy Critter Genetic Variation lab, students will analyze data and identify patterns in how traits in a population can change over time. In nature, individuals of the same species are not alike. They will differ in some way genetically. We call these differences in appearance and behavior, genetic variations. The traits you see expressed in an organism is called the phenotype. In this activity, the phenotype being looked at closely is the color of the "candy critter"
