So in your Bison example; there is evidence of domesticated cattle in the genotype(DNA) but there is no evidence of that unless you actually look at the genetics.

Does that make sense?
Well said thank you.

I guess then you enjoy a little microbiology from time to time, at least your response seems to indicate this.

Now mitochondrial DNA is another story all together and I have left out the DNA on the Y chromosome that we can identify certain traits of paternity by.
I am interested in this because many articles that I have read in the last year about authorities finding dead animals and identifying them as belonging to a group of wolves were deemed very costly. They seemed to look at all three types of DNA from my understanding.

Of course I had the unfortunate experience of trying to explain mitochondrial DNA to someone who ended up laughing and telling me that cells did not breath. Our french expression "respiration cellulaire" had thrown her for a loop. It takes specialists to translate scientific texts. I did do translation for a while but had a really big book to look up all the terms in (on loan from my local university). I thank you for coming in and helping me put this into words.

Yet on many forums (did not see the subject here) people said identification of an animal as part wolf was impossible. Maybe it is presently impossible for your ordinary citizen. I wish a group like Nature would explain this or a project like the Human genome project would exist for wolves. My understanding is that it is possible but costly and three tests need to be done to look for markers. However I am unaware how far the mapping of the genome of the wolf has been completed and am looking for info on this subject.

If you have a good understanding of the other types of DNA I'll let you explain you seem to do it quite well. Since my stroke I am wary of being called on the wrong word ect.


Found this and decided to add the link. I remember reading that for some reason doggy DNA had something very specific about it that permitted us to create so many breeds so rapidly. I was trying to find what this was called again. Then I ran into this article and looks like the version of the Human Genome Project for dogs is not such a bad idea after all.

http://www.plosbiology.org/article/i...l.pbio.1000451 Article speaks of how the phenotype of a dog is influenced by few quantitative trait loci.

With so few quantitative trait loci implicated in the phenotype of a dog it becomes easily manipulated through human selection in just a few generations.
