In which choice variable expression in mithochondrial diseases is best explained? Select one: D a. Imprinting D b. Locus heterogeneity c. Heteroplasmy d. Heterozygosity

The best explanation for choice variable expression in mitochondrial diseases is:<br /><br />c. Heteroplasmy<br /><br />Heteroplasmy refers to the presence of both normal and mutated mitochondria within a cell or organism. This variation in mitochondrial DNA can lead to differences in the expression of mitochondrial diseases, as the proportion of mutated mitochondria can influence the severity and presentation of the disease.
