Polydactyly is not specific to certain genetic conditions. It is an inherited condition for those who stick their fingers or toes into orifices where the sun don't shine. The fertilising secretions located in the said orifices attach themselves to the inserted digit. Under extreme and persistent circumstances the said digit then forms an alliance with the mating secretion and forms a further digit attached to the digit's limb. The condition is particular prevalent on those Rsholes who persist in the practice of trawling sites to create crabby comments and is a common source of webbed fingers and feet. This condition is commonly found in the muddy recesses South of the river..
