Assembly sizes include estimated gaps.
aStatistics based on chromosomes 1–22, X, Y and mitochondrial DNA of Han1 (CHM13 reference-guided assembly).
bStatistics based on primary contigs of HG00621 hifiasm de novo assembly.
cStatistics calculated directly from the T2T-CHM13 assembly, v2.0.
dStatistics taken from Table 1 and results of Yang et al. (2022).
eStatistics calculated directly from the YH2.0 assembly, downloaded from NCBI at https://www.ncbi.nlm.nih.gov/assembly/GCA˙000004845.2/.
fStatistics taken from Table 1 and Supplementary Table S2 of Lou et al. (2022).
gStatistics calculated directly from the ZF1 assembly, downloaded from the ZF1 Genome Sequence Archive page at https://ngdc.cncb.ac.cn/bioproject/browse/PRJCA000936.
hStatistics calculated directly from the GRCh38 assembly, downloaded from NCBI at https://www.ncbi.nlm.nih.gov/assembly/GCF˙000001405.26/. Statistics calculated using the primary assembly only, excluding alternative scaffolds. Scaffolds were split into contigs at position where the number of Ns was greater than 10.
