Links in the Haplogroup column lead to the haplogroup page to which the snp belongs. Links from RefSNP ID (aka rs numbers)
leads to data from the National Center for Biotechnology Information (NCBI) website. Links from the Y-position NCBI36 (UCSC hg18)
lead to the Family Tree Y-DNA Chromosome Browser designed by Thomas Krahn. Links from the Y-position GRCh37 (UCSC hg19) lead to
the UC Santa Cruz browser. Chromosome Y locations based on GRCh37 are different than those based on NCBI36.
