The allele for albinism is recessive to the allele for normal skin pigmentation. All individuals who are  homozygous for this recessive allele (m) are unable to produce the enzyme needed for melanin production and are  referred to as albinos. In the following statements, determine the correct genotypes: An albino male (genotype A)  whose parents both have normal skin pigmentation (genotype B) marries a woman who does not have albinism  (genotype C). This woman’s father is an albino (genotype D). The married couple has three children, two with  normal skin pigmentation (genotype E) and one exhibiting albinism (genotype F)

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.
