Question 1
In animals, mitochondrial DNA is inherited:
◦ equally from both the male and female parents.
◦ about 2/3 from the male parent and 1/3 from the female parent.
◦ about 2/3 from the female parent and 1/3 from the male parent.
◦ from the female parent only.
◦ from the male parent only.
Question 2
Mitochondrial DNA mutations accumulate:
◦ very rarely in multicellular eukaryotes.
◦ at a relatively high rate in all multicellular eukaryotes.
◦ more rapidly in mammals and less rapidly in plants.
◦ more rapidly in plants and less rapidly in mammals.
◦ only when the organism is exposed to DNA damaging conditions.
