Pedigree illustrating the relationship of cheetahs #1 to 4 used for the determination of the mitochondrial genome, the transmission of the myelopathic phenotype and the heteroplasmy G14,175A. Cheetah #3 is presented with the myelopathic phenotype after developing neurodegenerative symptoms in the course of the study. Square: male; circle: female; white: health status unknown; black: myelopathic; grey: non-myelopathic; w: wild-born (Namibia); HP−: homoplasmic at 14,175 (wild-type, 14,175G); HP+: heteroplasmic at 14,175 (G14,175A); n.a.: not analysed (no material available).
