Exploring Mendelian Genetics and Inheritance Patterns

The video tutorial covers Mendelian genetics, focusing on Gregor Mendel's experiments with pea plants. It explains how Mendel discovered the basic principles of heredity, including dominant and recessive traits, through his work on flower color. The tutorial introduces Mendel's laws of inheritance: the law of dominance, the law of segregation, and the law of independent assortment. It also covers essential genetic vocabulary such as alleles, genotype, and phenotype, and demonstrates how to use Punnett squares to predict genetic outcomes.
