Why Do Corgi Mixes Always Look Like Corgis?

The video explores the genetic basis of corgi traits, focusing on their short legs caused by a dominant retrogene derived from the FGF4 gene. This gene, which affects growth factors, has been historically favored in breeding, leading to widespread dwarfism in certain dog breeds. However, this genetic trait also poses health risks, such as spinal disease. The video highlights the long-standing human preference for these traits and the ongoing scientific efforts to understand their implications.
