Is Pg causing these white tip tail feathers?

I believe I am helping people by providing them with accurate information, you said Columbian(Co) was responsible for the effect of the bird´s tail, I pointed out that no research done on known restrictors proves that and that to assert such claim would need to be further researched and studied, the same way you pointed out in a thread that the Faverolle breed does not carry Mahogany because of the known effect mahogany has on the breast of the males, and I agree with you on that account, because research done by scientist have proven that to be true,


In any case we can agree to disagree but name calling is such an awful way to disagree with someone, please refrain from doing so.

I could do exactly what you do and troll your posts ( you referred to another one of my posts) and then give a rebuttal to every post, but I will not. That would be unseemly behavior (narcissistic), so I will not do so.

I will give you an example of how this would work. In the first post, you indicated that the white edge on the tail feather was mottling. The next thing I would do is quote your answer and then say that you are wrong and that mottling is expressed as a white tip on the end of the feather. I would also add that your picture can not be an example of mottling because according to research by Admundson and Milne the white tip should be in an approximate ratio of one white tip to every two to five feathers. Matter if fact; the tail feathers on the rooster in question do not show the white edging in such a ratio- so your conclusion is not correct. There is no research that would support your position.

The next thing I would do is explain why the mottling pattern and the exchequer pattern are expressed by the same gene and that the difference between the two are modifiers. I would also indicate that the two could be alleles located at the same locus. I would continue with more information by discussing the role of mottling gene in the expression of the mille fleur secondary color pattern. This additional information does not help answer the original question. What is causing the white edge on a tail feather? But I would add this information for educational purposes and also because it would make the readers think I know more than others. (most of the above is narcissistic)

With respect to my post about the white edging in the tail feather.

I could go into a long and lengthy explanation for why I believe the columbian gene is causing the white in the tail feathers but even if I did- you would simply respond with the research does not support your conclusion. Why should I waste my time with a person that refuses to listen to reason. (narcissistic)

A reasonable person would ask why I believe the columbian gene expresses white edging in the tail feathers. I would then proceed to give my explanation that was based upon my meta-analysis of the published research on restrictors. But why waste my time- I do not think you would be willing to follow the reasoning. I showed evidence for white in the tail feathers on columbian birds and you instantly say no research indicates such expression. Even though the pictures indicate that columbian birds show white in the tail, you will not even consider such an explanation when there is ample evidence that indicates the columbian gene could be responsible for the edging. That is narcissistic behavior.

Maybe you should also consider this; there is no research that indicates columbian does not express itself in such a manner.

Also note that in this short string I did not initiate a debate directly with you and you did this two times- you are the one that initiated a debate. The fact that you initiated an argument over the subjects two times is narcissistic behavior. If I had not called you out, and the sting continued, you would still initiate debate on each post.

Like I said I do not have the time to go into great detail on everything I post. I can see in the future that I would spend much of my time debating you over my posts instead of answering questions.

I haven't counted the feathers, to get an estimated ratio - that's an interesting item to note for future reference....however, I don't think my bird meets that ratio, it looks like most (but not all) of his very few tail feathers are edged in white....

I remember reading somewhere, maybe in Van Dort's Chicken Colours book, that exchequer and mottling work similar, I sort of skimmed that section, because I don't currently have either of those....

I would be interested to hear your explanation of the columbian gene expressing white edging.... I read the edelras website, they have some great information and it's broken down really well. Anyway, last week I read something about the Db restrictors, is that what you're referring to? I'm new at this, so I may be getting it wrong, I'll go back to the website and review.... I can post the link to it, if anybody is interested. I think they are in NZ.... The information is really good.

I would like to hear that too, so far my experience on the subject(breeding for Co and Db) has not shown such effect and current research on columbian restrictors have yet to show such effect even in heterozygotes.
