A geneticist has a strain of diploid plants. The gene orders for two of the chromosomes in this strain are AB.CDEF and KL.MNO. He subjects the plants to x-ray treatments and induces a reciprocal translocation between these two chromosomes. The translocation chromosomes are AR.GNO and KL.MDEF.

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.
