Q-L456 was one of the project’s gift-markers. It was discovered in the process of SNP testing someone for M346 and L213 using traditional Sanger sequencing. For a long time, the project lacked anyone willing to take part in additional testing. Then during the BIG Y pre-sale, a member of the Fox family joined the project and agreed to test. We now know that Q-L456 is a branch of Q-Z780.
- Q-L330 (Eurasian)
- Q-Z780 (Native American)
So far, the geography of Q-L456 is restricted to the eastern coastline of the United States.
