Problem:
So, for a project I've been working on (different story), I've been looking at the HapMap Project, and their free online files. In their README file, they talk about how for each legend file for each chromosome/region, there is an rs id, an alelle coded 0, 1, and a base pair position.
Now it's fairly obvious after staring at this for a while that base pair position means where each nucleotide is located along the genetic sequence... is this correct?
And what do rs id, and the other words mean? Please describe in detail.
