Thousands of high-quality sequencing samples fail to show meaningful correlation between 5S and 45S ribosomal DNA arrays in humans
The ribosomal RNA genes (rDNA) are tandemly arrayed in most eukaryotes and exhibit vast
copy number variation. There is growing interest in integrating this variation into genotype …
