And the only absolute is that we do not have all the information we need. Ralph and I think along the same lines.
It doesn't necessarily even have to be a"throwback" it can be that this birds gene expression has combined in just the right way to mimic one of the ancestral birds.There is no way to know.
Scientists have already made chickens grow teeth and tails in experiments by turning genes that were there but dormant "ON"
I just have to give up... you keep trying to run all over the place over a very simple issue.
It is this simple. If the chick has pea/walnut and there are pea/walnut bird in the flock then it is the parent.
To try to throw in everything, anything else is being willingly obtuse.
I give the same answer I just gave- ask others who know chicken genetics about the comb issue.
I'm out....
