Comparisons of concordance rates in MZ and DZ twins allow the estimation of heritability, a measure of the percentage of population variation in a disease that can be attributed to genes. Which one of the following is NOT a problem with using twin studies to measure heritability?     somatic mutations can occur during mitosis in MZ twins after they separate into two embryos     determining if a pair of twins is MZ or DZ is not accurate     environment may be more similar for pairs of MZ twins than for pairs of DZ twins     methylation patterns may differ for pairs of MZ twins

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
