Question: What is Lehi's ancestry?
Lehi and his family are not Jews: They belong to the tribe of Manasseh
Genetic attacks on the Book of Mormon focus on the fact that Amerindian DNA seems closest to Asian DNA, and not DNA from "the Middle East" or "Jewish" DNA. However, this attack ignores several key points.
Lehi and his family are clearly not Jews. They belong to the tribe of Manasseh (Alma 10:3, 1 Nephi 5:14), and married into Ishmael's family, the tribe of Ephraim.  These tribes were carried away captive by the Assyrians, and did not contribute greatly to the current genetic mix of the Middle East.
Furthermore, the Middle East is located at the crossroads of three continents, and has seen a great deal of immigration, mixing, and intermarriage. To use modern Middle Eastern DNA as the "standard" against which to measure what Manasseh and Ephraim DNA must have been like 2600 years ago is not a scientifically sound approach.
- "The Prophet Joseph informed us that the record of Lehi, was contained on the 116 pages that were first translated and subsequently stolen, and of which an abridgement is given us in the first Book of Nephi, which is the record of Nephi individually, he himself being of the lineage of Manasseh; but that Ishmael was of the lineage of Ephraim, and that his sons married into Lehi's family, and Lehi's sons married Ishmael's daughters, thus fulfilling the words of Jacob upon Ephraim and Manasseh in the 48th chapter of Genesis..." - Erastus Snow, "Ephraim And Manassah, etc.," (6 May 1882) Journal of Discourses 23:184.
