The paternal relationship between Gustav Radke and his son Leo Radke is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MR.

The segmental (via DNA segment triangulation) and total DNA shared between MR and other confirmed descendants of JR/Wilhelmine Ernestine Grade is consistent with the expected ranges for their respective relationships. Since MR descends from JR/Wilhelmine Ernestine Grade through Gustav Radke and his son Leo Radke, the presence of significant shared DNA between MR and other known descendants of JR/Wilhelmine Ernestine Grade validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple JR/Wilhelmine Ernestine Grade through Gustav Radke to Leo Radke, and ultimately to MR, confirming this direct ancestral connection through multiple generations.
