Labrador Coat Color Genetics

The video tutorial covers the genetics of coat color in Labrador Retrievers, explaining the basic colors and the genetic loci involved. It discusses the interactions between different genes and how they affect coat color, including the concept of epistasis. The tutorial also explores breeding outcomes based on genotypes and introduces genetic testing for determining a Labrador's genotype. The video aims to provide a comprehensive understanding of how genetics influence coat color in Labradors.
