13.Which among the following statements is INCORRECT? A. All statements are correct B.Only one of the two gene copies present in an organism is distributed to each gamete (egg cell / sperm cell) because of the separation of homologous chromosomes and sister chromatids during meiosis. C. If a cross produces 100% heterozygous genotype, then all of the offspring will exhibit the dominant allele D.The arrangement of chromosomes in metaphase I and metaphase II in Meiosis is not random, therefore, the inheritance of a trait will not affect the inheritance of the other trait

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.
