A population of white leghorn chicken has the following dominant mutations: crested head, the condition of having elongated feathers on the crown of the head, is dominant to normal-feathered head naked neck, the condition having no neck feathers, is dominant to normal-feathered neck Both are unlinked autosomal genes. A rooster is heterozygous for both of these traits. It mates with a hen that is also heterozygous for both traits. What is the percentage of their offspring that are predicted to have a normal-feathered head and naked neck? (Round your answer to one decimal place). For full marks, your work must be clearly shown

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.
