Red-green colour blindness is a sex-linked trait. Red-green colour blindness (Xrg) is the inability to distinguish between red and green colours. The Xrg allele is recessive to the normal X-linked allele. A normal woman has a father who has red-green colour blindness. She had a child with a man who does not have red-green colour blindness. What is the probability they will have a son with red-green colour blindness?

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.
