Genetics in Action: Law of Independent Assortment

The video tutorial explains Mendel's experiments with pea plants, focusing on traits like seed color and shape. It introduces the Punnett square as a tool for predicting offspring genotypes for single and multiple traits. The concept of dihybrid crosses is discussed, where hybrid offspring display dominant traits. Mendel's law of independent assortment is highlighted, explaining how traits are inherited independently.
