Nuclear DNA (nDNA)

The nuclear genome...

 

Nuclear-mitochondrial pseudogenes (NUMTS)

NUMTS are copies of mitochondrial genes that have been translocated to the nuclear genome. After insertion into the nuclear genome, NUMTS may be fragmented and/or duplicated. When mistaken for authentic mitochondrial genes, NUMTS may mislead phylogenetic inferences (Nacer & do Amaral, 2017). On the other hand, comparisons of known nuclear NUMTS may help clarifying phylogenetic relationships.
