Randy Seaver at Genea-Musings (â€œI’m Puzzled by DNA Claims on â€˜Faces of Americaâ€™â€) writes about the fourth and last episode of â€œFaces of America,â€ a PBS documentary series investigating the ancestry of several famous people in America. This fourth episode included several different types of genetic genealogy to examine the ancestral origins and relatedness of the showâ€™s members.
1. Whole Genome Sequencing by Knome
The first type of genetic genealogy was whole-genome sequencing by Knome of Henry Louis Gates and his father. This analysis examined Henryâ€™s (â€œSkipâ€™sâ€) genome for medical conditions and physical traits, and also compared his DNA to his fatherâ€™s, thereby allowing them to deduce the entire DNA contribution from his deceased mother. This segment was actually quite moving, as Dr. Gates was able to establish this intimate connection to the mother that he and his father obviously missed very much.
