Though he has mainly worked in the fields of photography and genetic testing, he is best known for his pioneering work in genetic genealogy. Greenspan founded Family Tree DNA which was the first American company to offer genealogical DNA testing directly to the general public. He is currently the president and chief executive officer (CEO) and also the managing partner of Family Tree DNA's parent company Gene by Gene. Greenspan is also the project administrator of several surname DNA projects, and regularly lectures on the use of genetics in genealogy and on genomics. A Jewish American, Greenspan was born in Omaha, Nebraska to Maurice and Rosalie Greenspan.

This is usually accomplished on human mitochondrial DNA by sequencing the hypervariable control regions (HVR1 or HVR2), and sometimes the complete molecule of the mitochondrial DNA, as a genealogical DNA test. HVR1, for example, consists of about 440 base pairs. These 440 base pairs are compared to the same regions of other individuals (either specific people or subjects in a database) to determine maternal lineage. Most often, the comparison is made with the revised Cambridge Reference Sequence. Vilà et al. have published studies tracing the matrilineal descent of domestic dogs from wolves.

Forensic databases (without individual information, for frequency purposes): In genetic genealogy, Ysearch used to be the last sponsored database containing publicly submitted surnames and Y-STR haplotypes until its decommission on May 24, 2018, preceding by a day the implementation of the General Data Protection Regulation in the European Union, following a prolonged period of lacking support from its creator, Family Tree DNA. The database was founded in 2003 and reached 219 thousand records (among which 152 thousand unique haplotypes) before its shutdown. Other similar databases had disappeared earlier.

As of 2019, about 2.5 million MyHeritage DNA kits have been sold, making it the third most popular genealogical DNA testing company In April 2019, MyHeritage began releasing data from a new DNA chip. In May 2019, MyHeritage launched the MyHeritage DNA Health+Ancestry test, a test that provides comprehensive health reports to consumers. The Tribal Quest Expedition project is MyHeritage's pro bono project to record the family histories of tribal peoples. It also has a program to match descendants of Holocaust survivors with property taken from their family. In 2013, MyHeritage was selected by Globes as the most promising Israeli startup for 2013–2014.

short tandem repeatmicrosatellitesSTR
Paternally inherited Y-STRs (microsatellites on the Y chromosome) are often used in genealogical DNA testing. During the 1990s and the first several years of this millenium, microsatellites were the workhorse genetic markers for genome-wide scans to locate any gene responsible for a given phenotype or disease, using segregation observations across generations of a sampled pedigree. Although the rise of higher throughput and cost-effective single-nucleotide polymorphism (SNP) platforms led to the era of the SNP for genome scans, microsatellites remain highly informative measures of genomic variation for linkage and association studies.

The fact that human Y-chromosome DNA (Y-DNA) is paternally inherited enables patrilines and agnatic kinships of men to be traced through genetic analysis. Y-chromosomal Adam (Y-MRCA) is the patrilineal most recent common ancestor from whom all Y-DNA in living men is descended. An identification of a very rare and previously unknown Y-chromosome variant in 2012 led researchers to estimate that Y-chromosomal Adam lived 338,000 years ago (237,000 to 581,000 years ago with 95% confidence), judging from molecular clock and genetic marker studies. Before this discovery, estimates of the date when Y-chromosomal Adam lived were much more recent, estimated to be tens of thousands of years.
This is most true of genetic material that is subject to lateral gene transfer and recombination, where different haplotype blocks can have different histories. In these types of analysis, the output tree of a phylogenetic analysis of a single gene is an estimate of the gene's phylogeny (i.e. a gene tree) and not the phylogeny of the taxa (i.e. species tree) from which these characters were sampled, though ideally, both should be very close.
