Identical twins, identical DNA, different ancestry results? We put three kits to the test

MOBILE, Ala. (WALA) – Caroline and Camille Clarke are 7-year-old first-graders at Hutchens Elementary School in Mobile. Their favorite subject is science.
It shouldn’t be a surprise – they’re identical twins.
So the results of DNA tests should be exactly the same for both girls, right? To find out, FOX10 News had each girl take three of the most popular DNA ancestry kits on the market – Ancestry.com, 23andMe, and National Geographic.

Despite the Same DNA, Severity of Autism Symptoms Varies Greatly Among Identical Twins

Identical twins with autism spectrum disorder (ASD) often experience large differences in symptom severity even though they share the same DNA, according to an analysis funded by the National Institutes of Health. The findings suggest that identifying the causes of this variability may inform the treatment of ASD-related symptoms. The study was conducted by John Constantino, M.D., of Washington University School of Medicine in St. Louis, and colleagues. Funding was provided by NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). The study was published in Behavior Genetics on December 18, 2019.
