The paternal relationship between Carl Habeck and his son Ferdinand Habeck is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JH.

The segmental (via DNA segment triangulation) and total DNA shared between JH and other confirmed descendants of Christoph Rakow/ALS is consistent with the expected ranges for their respective relationships. Since JH descends from Christoph Rakow/ALS through Carl Habeck and his son Ferdinand Habeck, the presence of significant shared DNA between JH and other known descendants of Christoph Rakow/ALS validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Christoph Rakow/ALS through Carl Habeck to Ferdinand Habeck, and ultimately to JH, confirming this direct ancestral connection through multiple generations.
