In some breeds of dogs, a recessive allele (a) codes for color dilution alopecia, a condition in which the hair color appears blue or gray due to an uneven distribution of melanin in hair follicles. The dominant allele A codes for undiluted hair color (black). In one population of dogs in the southeastern U.S., the frequency of the A allele was determined to be 0.71, with the frequency of the a allele being 0.29. Calculate the frequency of the aa genotype in the next generation.

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.
