  1. Summary of sequence class coverage of HG02982 versus GRCh38, as well as the contigs from NA23385 identified as derived from the Y chromosome. The proportion of recovered sequences and % identity are calculated over the resolved sequences in GRCh38, excluding gaps. There are currently 30.8 Mb of unresolved sequence (represented by the ambiguous base N) in the reference Y chromosome of GRCh38, the vast majority of which belongs to heterochromatin on the q arm
  2. Aln.: aligned bases to GRCh38, ID.: percent identical bases in GRCh38, Rec.: recovered proportion from GRCh38, Len.: length in GRCh38
