The OP has a cleanfaced roo and was told that it was split for tufts.  Not possible.

 

I have a couple of split wheaten araucanas which means that they are e+/ewh, which is half wild type and half wheaten as I understand it.

 

A lavender has to have two copies of the lavender gene to express the color, so a lavender split would be half lavender and half black, but the black is dominant and its the color that shows on the body.

If they're sex-linked, and we're talking about hens, then having it on her one Z means she has it on her only Z. The Z is paired to W, so on this "pair", if it is on that Z, then it is on "each member of the pair of chromosomes on which they exist" since it doesn't "exist" on the W.

 

I was trying to be as concise as possible -- I have a habit of being too verbose.

Ah-HAH! Someone who understands my insanity. That means you're kinda crazy, too. Me like.

Not if they are recessive sex links....lol.png

A recessive sex-linked gene is an allele which is not expressed in the presence of an allele which is dominant to it. In order for it to be an allele, it must exist on the other member of the pair in the same position. If the pair is composed of two different chromosomes (ZW), then there is no "same position" available in the other member of the pair. Thus when a hen has a recessive sex-linked gene, all members of the pair have the recessive allele on the chromosome on which it exists -- in this case, since there's only one Z, there is only one member of the pair with the locus, and thus only one copy is necessary.
