What I intend is the science of genetics has undergone a very rapid and significant development in the recent years, and the area of poultry genetics has been no exception, it go from Mendelian to modern molecular genetics, aspects as poultry genetics, cytogenetics, transmission genetics, gene mapping, sex linkage, lethal genes, genetics of feathering and plumage, quantitative genetics. Short said the evolution of the domestic fowl (Gallus domesticus) from its avian ancestors until today.
We should take use of it.
