Thanks for clarifying the autosome / sex-linked inheritance!Autosome genes are passed down to the future generation from both parents ,regulated by the rules of dominance .
Sex linked genes are different ,Mama hen passes her sex lined genes to her sons only .
the Sire will passes his sex linked genes to both his progeny boys and girls .Example /silver cuckoo hen mated to solid black rooster = all the male progeny will be dark cuckoo and all the females progeny will be solid black .
but a silver dark cuckoo { one copy of the cuckoo gene} rooster mated to a solid black hen =50% cuckoo and 50% solid black . boys and girls .
sex linked genes are very complicated .
