Right:

In the collage-image is an F2 (3rd generation X 3rd generation) gold laced naked neck polish cockerel and a pair of F1 (50/50 mix) pullets that will be bred to create 2nd generation Sully's Island Chickens.  The cockerel is bearded, so that will have to be selected against in subsequent generations.  "But he has no beard," I can imagine you asking. Let me explain. The beard/muffs gene in chickens is incomplete dominant. What that means is that a chicken that is heterozygous for the gene will (typically) have a smaller beard and muffs, whereas a chicken that is homozygous for the gene will have a full beard and muffs. This cockerel's father also is heterozygous bearded, but because of how the incomplete dominant naked neck gene affects the beard/muff phenotype, neither the father nor his son  express beard/muffs.  The interaction between beard/muffs and the naked neck gene is inconstant, I have observed. Some birds (regardless of gender) that are heterozygous for both will have muffs without a beard, a full beard and muffs, or a completely featherless face and chin. Based on my observations of other breeds, the gene for a dewlap is closely linked to the gene for beard/muffs. For this reason, you rarely ever see a bearded bird without a dewlap, but there are breeds (such as Araucana) that have a dewlap with no facial "hair". These birds have small or non-existent wattles.  In my four years of closely observing chickens, I have not seen a chicken that has large wattles AND that is simultaneously homozygous for a dewlap. This brought me to the conclusion that non-expressed heterozygous beard/muffs can be identified by looking at the size of a chicken's wattles. This cockerel (as does his naked-faced father) has small slightly wrinkled wattles. His full blooded sister has a beard with muffs. For these reasons, I can say with very high certainty that the cockerel in the above/right image is bearded.
