Galactosemia is a rare autosomal recessive disease that causes mental retardation. Individuals with galactosemia never reproduce. In a large human population the frequency of individuals with galactosemia is 1 in 118 000. Calculate the rate of mutation to the galactosemia allele, assuming mutation-selection equilibrium in the population.

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.
