this might help some to answer
There are three known genes which cause leg feathering -- Pti-1, Pti-2, and pti-3. ("Pti" stands for "ptilopody", which means "foot feathering" or, I suppose more accurately, "feather-footedness").
Pti-1 and Pti-2 are dominant genes. Therefore, it only takes one copy of these genes to produce leg feathering.
Pti-3 is a recessive gene. Therefore, it takes two copies of this gene for pti-3 to produce leg feathering. I have heard that this gene is only present in a breed called Pavloff, but I don't know whether that is true or not.
There also appears to be at least one "feather foot inhibiting gene". This gene (or set of genes) doesn't seem to have a widely accepted label -- and from the small amount I've read about it, it isn't really clear whether this inhibitor is a simple recessive trait or not. If it is recessive, then it would take two copies of this gene to produce its full effect -- and the trait would have to be inherited from BOTH parents. HOWEVER, for all I know this gene might actually be an incomplete dominant -- meaning that it might inhibit leg feathering a bit if there were one copy of the gene, and inhibit leg feathering further if there were two copies of the gene.
