Albinism is characterized by the lack of a dark pigment called melanin in the hair, skin and eyes.  Albinism is caused by the absence of an functioning enzyme called thyrosinase, which is necessary for the synthesis of  melanin.  Given this bit of information, what can you assume about the heredity pattern of this trait? A) It is caused by a recessive allele of the gene coding for thyrosinase. B) It is caused by a dominant allele of the gene coding for melanin. C) It is caused by a dominant allele of the gene coding for thyrosinase. D) It is caused by a recessive allele of the gene coding for melanin. E) There is not enough information here to tell

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.
