Exploring Genetics and Probability Concepts

The video tutorial covers the basics of genetics, including the study of how traits are passed from parents to offspring. It introduces Gregor Mendel's experiments with pea plants, which laid the foundation for modern genetics. The tutorial explains the role of DNA and chromosomes in carrying genetic information and describes the concepts of genes, alleles, dominant and recessive traits. It differentiates between genotype and phenotype and demonstrates how to use Punnett squares to calculate the probability of inheriting specific traits.
