The International Society of Genetic Genealogists is an ad-hoc group that formed out of the hotbed of genetic genealogy among the Southern California Genealogical Society (SCGS) and similar groups from Los Angeles down to San Diego. Their biggest recognition to date has been their online, constantly updated yDNA Phylogenetic tree that they took over from YCC when that ad-hoc group ceased as an entity and ISOGG was born to continue that effort. ISOGG have no real organizational structure other than the website presence.
They have since expanded with a Wiki which recently has seen extensive work to expand and un-bias their early material there. The wiki often contains dates that pre-date their appearance in the public wiki by many years. It is believed they are transferring some material from an internal site located somewhere else.
The site is the home for the yBrowse SNP database application to register and define SNPs as found in the Y chromosome. This is really a sole effort of Thomas Krahn and his ySeq enterprise. But posting it as a sub-domain of ISOGG brings some legitimacy and appearance of independence.
Note: ISOGG and SCGS are separate entities with the former being ad-hoc. SCGS is by far a much larger, more organized, enterprise with assets; and a general genealogy organization.
Further note: The ISOGG tree did lag for a number of years in the mid-2010 decade but has since been re-energized and pushing ahead further. Their academic, published paper approach to expanding the tree that started with YCC is admirable but overtaken by the ad-hoc, citizen-scientist, dynamic expansion seen by the other sites. Both have a place for now but generally other sites are more refined in their trees.
