Brown eyes are dominant over blue. This is NOT a sex-linked trait. If a blue-eyed colorblind woman marries a normal visioned man who is homozygous for brown eye color, what kind of children might they expect with respect to these two traits? Genotype of woman Genotype of man What two genotypes are possible in the children? If one of the sons in turn maries a heterozygous brown-eyed, normal visioned woman, not a carrier, what kinds of children might they expect? Genotypes Phenotypes

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.
