In this video, Ricardo Dornas reveals an impressive scientific discovery: feathering is controlled by different genes that act in completely different ways. While one gene signals the organism to produce common cover feathers on the leg, another gene simply "tricks" the bird's system, causing the body to treat the leg as if it were a wing and legitimate flight feathers (remges) to grow. To access more applied genetics content and organize the control of your birds, visit our official website: www.chacaradornas.com.br. Understand how these mutations act on the chromosomes of breeds like Brahman and learn to visually identify which of these mutations is present in your breeding stock. Ricardo also explains the action of other key genes, such as fibromelanosis (which directs black to the entire body and organs, as in Silkies) and the use of the Dark Brown gene to fix the beautiful Red Pyle color by clearing eumelanin from the tail. Discover how to use science to your advantage in selecting your flock to achieve the perfect show standard. Topics covered in the video: The Science of Feathering on the Feet: How two dominant genes and one rare recessive gene determine the presence of feathering on the shanks. The Genetic Trick of the Wing: The mutation that makes the bird's organism "confuse" the foot with a wing, generating flight feathers on the legs. Fibromelanosis in Focus: How the hyperpigmentation gene acts on melanocytes to color the skin and tissues of birds. Creating the Red Pyle Pattern: The combination of the Dark Brown gene with the Dominant White gene to isolate pheomelanin and lighten the tail. Black Crossbreeding: How the recessive white gene can remain hidden in dark lineages and surprise the breeder with 25% white chicks. #PoultryGenetics #Feathering #BrahmaLight #ChacaraDornas #Fibromelanosis #RedPyle #GeneticImprovement #FertileEggs #ChickenRaising #ElitePoultry #PoultryMorphology
