The breed falls under the mitochondrial DNA sub-clade referred to as d1 that is only found in northern Scandinavia. It is the result of a female wolf-male dog hybridization that occurred post-domestication.
Paternal mtDNA inheritance in animals varies. For example, in Mytilidae mussels, paternal mtDNA "is transmitted through the sperm and establishes itself only in the male gonad." [2] [3] [4] In testing 172 sheep, "The Mitochondrial DNA from three lambs in two half-sib families were found to show paternal inheritance."
An IVF technique known as mitochondrial donation or mitochondrial replacement therapy (MRT) results in offspring containing mtDNA from a donor female, and nuclear DNA from the mother and father. In the spindle transfer procedure, the nucleus of an egg is inserted into the cytoplasm of an egg from a donor female which has had its nucleus removed ...
Homoplasmy is a term used in genetics to describe a eukaryotic cell whose copies of mitochondrial DNA are all identical. [1] In normal and healthy tissues, all cells are homoplasmic. [2] Homoplasmic mitochondrial DNA copies may be normal or mutated; [1] however, most mutations are heteroplasmic [2] [3] (only occurring in some copies of ...
Therefore, male-specific deleterious mtDNA mutations could be maintained and reach a high frequency in populations, decreasing males' fitness and population viability. In addition, the effect of mtDNA mutations on fitness has a threshold effect, i.e. only when the number of mutation reaches the threshold, mtDNA mutations will decrease ...
