Exercise
Genetic Variation and Alleles
Explore the fascinating world of genetics in this engaging exercise, where students will investigate the role of genetic variation and alleles in inheritance by analyzing real-life examples and engaging in hands-on experiments to understand how traits are passed from one generation to the next. Unleash your inner scientist as you discover the building blocks of life!
