The classical twin study is established as the definitive study design for investigating the relative importance of genetic and environmental factors to traits and diseases in human population. Monozygotic (identical) twins share all of their genes, while Dizygotic(fraternal) twins share only about 50 percent of them, the same as non-twin siblings. If a researcher compares the similarity between sets of identical twins to that of fraternal twins for a particular trait, then any excess likeness between the identical twins should be due to genes rather than environment. Write an information leaflet evaluating the benefits and dilemmas in the use of human twin studies to investigate the causes of variation.

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.
