What is the process for using an ancestry spit kit to trace your family's lineage?

To use an ancestry spit kit to trace your family's lineage, you first need to purchase a kit online or in a store. Then, follow the instructions to collect a saliva sample by spitting into a tube. Mail the sample back to the company for analysis. Once the results are ready, you can access them online to learn about your genetic ancestry and connect with potential relatives.
