HumanCode scientists developed a trait prediction methodology that allows us to combine the DNA of two people and make trait and ancestry predictions of their potential future children. Our team researched hundreds of scientific papers to find well-studied traits that were part of large, publicized findings with as much ethnic diversity as possible. This helped us narrow our focus to over 20 fun and informative traits. These traits range from physical characteristics such as eye color, hair color, adult height, or being prone to freckles to preference indicators such as favoring sweet snacks. For ancestry prediction, we use informative ancestry markers across your DNA to tell us where your family came from.
