Figure 4From: The mitochondrial DNA control region shows genetically correlated levels of heteroplasmy in leukocytes of centenarians and their offspringLinear regression of heteroplasmy levels in parent-offspring pairs according to the sex of the parent: (a) male centenarian parents; (b) female centenarian parents. The regression lines showed r = -0.053 (p = 0.704) and r = 0.456 (p = 0.001) in (a) and (b), respectively.Back to article page
