Mitochondrial DNA haplotypes and mating outcomes

A few years ago I did a lot of work on mitochondrial DNA. This is the DNA that is inherited matrilineally - that is - the female passes it on to her sons and daughters but only the daughters then pass it on to the next generation. Setting aside the physiological importance of mitochondrial DNA (mtDNA), it is also important from a historical perspective as it allows us to examine an individual and group them by their mtDNA haplotype, as this haplotype remains relatively unchanged for thousands of years and traces back through to a single source. Back in 2012 an academic group out of Italy examine a vast array of equine breeds and catalogued their mitochondrial DNA, using the genetic changes t
