Ancestry kits are DNA testing products that help individuals discover their genetic heritage and family history. By analyzing a sample of saliva or cheek cells, these kits can provide insights into a person's ethnic background and potential ancestral origins. Many companies, such as AncestryDNA and 23andMe, offer these services, making it easier for people to connect with their roots. In addition to ethnicity estimates, ancestry kits often include features like family tree building and connections to potential relatives. Users can explore historical records and genetic traits, enhancing their understanding of their lineage and the broader context of their ancestry.
