Exploring Mendelian Genetics Concepts

The video provides an introduction to genetics, focusing on Mendelian genetics and the work of Gregor Mendel. It recaps the processes of mitosis and meiosis, highlighting their roles in cell division and genetic diversity. The video delves into Mendel's experiments with pea plants, explaining how he discovered the concepts of dominant and recessive traits. It also covers the differences between genotype and phenotype, and the role of alleles in genetic variation.
