THE SILVER IN THE SILVER LACED IS A SEX LINKED DOMINANT GENE

In poultry the sex of any chick is determined by the hen not the cockerel. The cockerel carries two Z chromosomes so he is ZZ. The hen carries one Z chromosome and one W chromosome so she is ZW.The cockerel must pass one of his Z chromosomes  onto his offspring so any sex linked genes that are on that chromosome such as Silver, Bantam, Barring and Chocolate will be inherited. The hen can pass either her Z or her W chromosome on to her offspring. If she passes her Z chromosome on her chicks will be male and they will inherit all the sex linked genes that are on that Z   chromosome but if she passes her W chromosome on,  her chicks will be female and they will inherit none of the sex linked genes she is carrying. Genes that are sex linked can only be carried on the male chromosome.
