17) There is a hypothetical gene in mice that produces a substance that induces twitchiness in hind leg muscles. A female mouse of a true-breeding twitchy strain is mated with a male of a true-breeding non-twitchy strain. All progeny are twitchy. Twitchiness may simply be a dominant trait caused by a nuclear allele, or it could be due to mtDNA. How would you distinguish between these two possibilities? Include possible results and how you would interpret them.
