Understanding Alleles and Genes

The video tutorial explains the difference between genes and alleles. Genes are sections of DNA that code for specific traits, such as eye color or metabolism. Alleles are different forms of the same gene, akin to different flavors of a product. The video uses analogies to clarify these concepts and emphasizes that while genes determine traits, alleles specify the form those traits take. The tutorial concludes by inviting viewers to explore more genetics videos and ask questions.
