Well, no biggy.
It is just that we had some wheaten/e^b serama crosslings that started out showing the e^b typical barring pattern but ended up typical wheaten looking.
I started a topic on the-coop about it a while ago.
Perhaps with a bit more melanizers the experiment would have turned out...
e^b, e^s and e^bc are similar if not the same, also in order of dominance.
e^wh and e^y are both wheaten and were DNA sequenced. They have the same code.
I would not worry about differences between the two. One wheaten explains all.
There is also more than one birchen allele...
Carefoot also...
