Fundamentals of Genetics: Summing Up

The video tutorial explores the fundamentals of genetics, starting with Gregor Mendel's principles. It covers dominant and recessive traits, phenotypes, and genotypes. The differences between homozygous and heterozygous genes are explained, followed by an introduction to the Punnett Square and hybrid crosses. The concept of using probability to predict genetic outcomes is discussed, and the tutorial concludes with a reflection on observing genetic traits in everyday life.
