hello. what does it mean.

Public Haplotree.
snips and big y?

I was taking you seriously until I saw the "Britney Spears Bares All" link at the end.

Anyway, this is from NIH.gov Primer:SNP:

Single nucleotide polymorphisms, frequently called SNPs (pronounced “snips”), are the most common type of genetic variation among people. Each SNP represents a difference in a single DNA building block, called a nucleotide. For example, a SNP may replace the nucleotide cytosine (C) with the nucleotide thymine (T) in a certain stretch of DNA.

SNPs occur normally throughout a person’s DNA. They occur once in every 300 nucleotides on average, which means there are roughly 10 million SNPs in the human genome . . .

By comparing a man’s SNP test results to the Y- chromosome reference sequence maintained by the Genome Reference Consortium, his set of SNPs can be identified and named.

Comparison to the results of other men is used to detect matches who share the same Y- chromosome ancestor.

The closer the match, the more recent the shared Y-chromosome ancestor.
