We've been exploring the new #T2T human genome assembly compared to previous versions (our news and views article is out today, link below). Some observations: (1) Its pretty amazing what the human genome project was able to do in 2004: large-scale gene order is totally conserved (2) Some of the chromosomes are nearly identical between the 2013 GRCh38 assembly and T2T. For example, here is a zoom in on Chr10 - just a few gaps in the pericentromere that were filled in with tandem repeats in T2T.
