The sequencing and assembly of the human Y chromosome have been challenging due to its intricate repeat structure, which encompasses lengthy palindromes, tandem repeats, and segmental duplications. The existing GRCh38 reference sequence lacks over half of the Y chromosome’s content, leaving it as the final unfinished human chromosome. Addressing these limitations, the Telomere-to-Telomere (T2T) consortium…
