How is it still balanced if, let's say we have 100% chromosome A and 100% chromosome B. In simple translocation, 25% of chromosome A moves to chromosome B, to get 125% genetic material. This is unbalanced (I am referring to individual chromosomes). Together, we still have 200% genetic material but individuall it is not

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.
