Chapter 5, Problem 28CONQ

Extranuclear inheritance often correlates with maternal inheritance. Even so, paternal leakage may occur. What is paternal leakage? If a cross produced 200 offspring and the rate ofmitochondrial paternal leakage was 3%, how many offspringwould be expected to contain paternal mitochondria?
99% of mitochondria are inherited from the mother. Mitochondria are thus primarily passed on from mother to offspring. Draw a pedigree showing a pattern that suggests a mitochondrial gene mutation.
Explain step by step.
Within one nucleoid, is the mitochondrial chromosome found in a single copy or multiple copies?
