What patterns in a pedigree characterize a trait determined by the mitochondrial genome?

Question

Quizplus · Accepted Answer

A trait determined by the mitochondrial genome is inherited maternally, meaning that it is only passed down from mother to offspring. Therefore, all offspring of an affected female will show the trait. Additionally, since mitochondrial DNA is only passed down from the mother, males do not transmit the trait to their offspring, but can still be affected by the trait themselves. Therefore, the pattern in a pedigree for a mitochondrial trait would be that all offspring of an affected female show the trait, and males never transmit the trait to their offspring.
