Branco Dominante ou Recessivo? Como Testar Suas Galinhas Brancas

📘 Secure your copy of the Poultry Genetics Treatise here: https://go.hotmart.com/R106024761W?dp=1 In this Q&A session, Ricardo Dornas directly answers the main questions breeders have about practical genetic testing, demystifying the behavior of complex colors and the hidden saboteurs in the flock. Learn the step-by-step process of how to cross a white bird to discover if it carries the Dominant White (I) or Recessive White (c) gene, using strategic mating with red or yellow birds to reveal the hidden genotype.

The video also details the process of introducing the Barred gene into Buff lines to obtain the very rare Yellow Barred, as well as revealing the "secret" behind the Millefleur pattern. Understand why the perfect Mille Fleur pattern necessarily requires the homozygous combination of the recessive Mottled (mo) gene working in harmony with the Columbia (Co) gene, which pushes black eumelanin to the extremities and creates the iconic visual of white tips and dark bars on a brown background. Finally, discover how undesirable defects, such as green shank (a sex-linked recessive gene) and weak feathering on the legs of heavy breeds, act as silent saboteurs transmitted by perfect heterozygous males. Topics covered in the video: White Test: How to visually differentiate Dominant White from Recessive White through crossbreeding. Yellow Barring Fixation: Practical crossbreeding from Buff hens and recognition of the spot on the chicks' heads. Silent Saboteurs: How the green shank gene and feathering modifiers hide in males. The Mille Fleur Formula: The essential zootechnical interaction between the Mottled gene and the Columbia gene. Importance of Culling: Why insisting on birds with genetic modifier defects maintains the flaws in your flock. #PoultryGenetics #MilFlores #DominantWhite #ChacaraDornas #ChickenManagement #GeneticImprovement #Mottled #GreenShin #FertileEggs #EliteBreeding #YellowBarred
