POLYGENIC INHERITANCE - [Action of Several Genes]
Learn how multiple genes can influence traits such as height, skin color, and other phenotypic characteristics. Discover how this form of inheritance adds depth and variability to genetics, and how scientists study these patterns to better understand our biology.
