Genetics Concepts and Terminology

This video tutorial introduces basic genetic terms essential for understanding heredity. It covers the concept of heredity, explaining how traits are passed from parents to offspring through genes. The video discusses genes, alleles, and their variations, and explains the terms heterozygous and homozygous. It also covers dominant and recessive traits, and the differences between genotype and phenotype, providing a foundational understanding of genetics.
