Decoding DNA can provide valuable insights into our ancestry, health, and genetic predispositions. There are different types of DNA testing available, each offering unique benefits and applications. Understanding the differences between these tests can help you choose the right one for your specific needs.

Types of DNA Testing

1. Autosomal DNA Testing: This type of testing examines the 22 pairs of autosomal chromosomes, which contain a mix of genetic material from both parents. It is useful for exploring ancestry and finding relatives across multiple generations.
