The intricate relationship between biblical genealogy and DNA patterns revealed in the Torah presents a fascinating reexamination of traditionally accepted family lines. Although Genesis 6:10 explicitly states that Noah had three sons: Shem, Ham, and Yopheth - a deeper analysis of genetic markers described in the Torah suggests a more complex reality behind these relationships. The careful documentation of these genetic patterns in the Torah suggests the importance of genetic heritage in establishing legitimate lineages. This understanding helped maintain accurate records of important bloodline.
