The founder of the array of F3'5'Hs on chr6 was initially duplicated through tandem gene duplication.
From this initial chromosome organization, the ancestral diploid genome was duplicated through Whole-Genome Duplication (WGD) then fragmented giving rise to an intermediate ancestor with 2n = 2× = 24 chromosomes [ 11].
Trans-NATs expressed antisense of pseudogenes can be duplicated through events of genomic duplication.
