Thanks, I guess I'm not using terminology correctly. I knew from other readings what you have written... It is very understandable.
I guess I was just using SNP as a name instead of a name / action?? "single nucleotide polymorphism". so a nucleotide ( one of the A, C, G, or T) at a particular placement on a chromosome, changes either by replacement of it by one of the other nucleotides or by its disappearance. So would you say the nucleotide polymorphs instead of the SNP mutates?
Single = One
Polymorphism = In general, polymorphism describes multiple possible states for a single property
So in my limited knowledge a particular (singular) nucleotide (one of A,C,G,T) can change into any of the others, or just be dropped off. So then the nucleotide isn't being named, only the placement and the action it took is named...?? (example - EA's S116) and you either have it (the change / mutation / polymorph) (+ derived) or you don't (it is the same as it used to be no change)(- ancestral).... So do I have it?? nelda
