Segregation of Tay-Sachs and Sandhoff alleles in a non-Jewish family.

abstract：:The standard paradigm postulates that the human mitochondrial genome (mtDNA) is strictly maternally inherited and that, consequently, mtDNA lineages are clonal. As a result of mtDNA clonality, phylogenetic and population genetic analyses should therefore be free of the complexities imposed by biparental recombination....

Combined with other familial studies, our results add up to 18 substitutions in 1,729 transmissions ...
