For the Mytilus phenomenon look at
Zouros,Eleftherios, Freeman, K. R., Oberhauser Ball, A., Pogson, G. H. 1992.
Direct evidence for extensive paternal mitochondrial DNA inheritance in the
marine mussel Mytilus. Nature 359:412-414
Skibinski, D. O., Gallagher, C., Beynon, C. M. 1994. Sex-limited
mitochondrial DNA transmission in the marine mussel Mytilus edulis. Genetics
138(3):801-809
and papers in MBE by Zouros' group (Walter Hoeh, Donald Stewart and others)
The male and female mytilus inherit mtDNA from both parents, but then
development in either sex leads to a dominance of one mtDNA haplotype per
sex. In Mice and Drosophila, the observed mtDNA heteroplasmy is attributed
to "leaky" sperm, quite a different situation than Mytilus (assuming I'm
remembering all this correctly, it's been awhile since I read all this
stuff)
