Genetic Concepts and Terminology

This video tutorial from MooMooMath and Science introduces key life science vocabulary, including alleles, homozygous, heterozygous, chromosomes, and genes. It explains each term with definitions and examples, illustrating how alleles represent different forms of a trait, and how homozygous and heterozygous genes differ in allele composition. Chromosomes are described as DNA bundles carrying genetic information, while genes are sections of DNA with instructions for protein synthesis. The video concludes with a call to action for viewers to subscribe and share.
