Egypt represents an ideal location for genetic studies on population migration and admixture due to its geographic location and rich history. However, there are only a few reliable genetic studies on ancient Egyptian samples. In a previous study, we assessed the genetic history of a single site: Abusir el-Meleq from 1388 BCE to 426 CE. We now focus on widening the geographic scope to give a general overview of the population genetic background, focusing on mitochondrial haplogroups present among the whole Egyptian Nile River Valley. We collected 81 tooth, hair, bone, and soft tissue samples from 14 mummies and 17 skeletal remains. The samples span approximately 4000 years of Egyptian history and originate from six different excavation sites covering the whole length of the Egyptian Nile River Valley. NGS based ancient DNA 8 were applied to reconstruct 18 high-quality mitochondrial genomes from 10 different individuals. The determined mitochondrial haplogroups match the results from our Abusir el-Meleq study. Our results indicate very low rates of modern DNA contamination independent of the tissue type. Although authentic ancient DNA was recovered from different tissues, a reliable recovery was best achieved using teeth or petrous bone material. Moreover, the rate for successful ancient DNA retrieval between Egyptian mummies and skeletal remains did not differ significantly. Our study provides preliminary insights into population history across different regions and compares tissue-specific DNA preservation for mummies and skeletal remains from the Egyptian Nile River Valley.
