I agree the name "beard AND muffs" is a confusing name. It implies they are two different things but as far as I know it's all due to only one gene.
They can vary a lot in appearance though, both to being pure or not pure for the uh.. 'beard/muff' gene and various other genes that help how this trait looks.
A few birds can have a really skimpy, mostly smooth laying 'beard' but decent 'muffs'.. others can have skimpy 'muffs' but an obvious, hanging 'beard' and everything in between. Birds with the beard/muff like yours are very common. Then there are a few with both the beard/muff very sparse and laying smooth against the face so they appear not to have it but surprise by throwing chicks with beard/muff.
Birds with very obvious 'separate' muffs & beards usually were bred that way to match show standard.. they may seem well defined but it's still the same gene, just 'looks a tad different as in more defined and much bigger'.
