Recent per-assembly metadata only; lifetime history is stored as compact aggregates.
Collection metrics
What do deposited genome assemblies contain?
Metadata-derived properties of the chromosome-scale and complete GenBank eukaryote collection. These metrics describe what is explicitly associated or labelled in NCBI records; they do not infer missing biological features.

Loading genometrics…
Organelle association
Mitochondrial genome associated
Share of all tracked genome deposits with an associated mitochondrial genome in the NCBI assembly record.
Plant organelles
Plastid genome associated
Share of tracked Viridiplantae genome deposits with an associated chloroplast/plastid genome in the NCBI assembly record.
Chromosome labelling
Sex-chromosome labels
Explicit X/Y/Z/W-style labels or explicitly identified other sex-chromosome names in NCBI sequence reports, across all tracked genome deposits.
Karyotype audit
Chromosome count vs expected
For species with Tree of Sex chromosome counts, compare the number of chromosomes represented by the NCBI assembly with the reported biological karyotype.
Assembly architecture
Genome size & contiguity
Collection-wide assembly size and contiguity from NCBI assembly statistics. This describes deposited assemblies; an independent biological genome-size reference can be layered on when sufficiently broad data are available.
Genome size
Chromosome number
Biological context
Ploidy & sexual systems
Reference traits represented among tracked species with Tree of Sex records. These describe organism biology rather than assembly quality.
Observed vs expected
Expected sex-chromosome annotation
For genome deposits from species with an explicit Tree of Sex karyotype, compare the expected sex-chromosome system with the labels actually present in NCBI sequence reports.
Expected system: Tree of Sex · observed labels: NCBI sequence reports.
Interpretation
What these metrics mean
Mitochondrial / plastid: an organelle is counted only when NCBI's assembly metadata explicitly associates that organelle genome with the nuclear assembly.
Sex chromosomes: expectations use species records first, then conservative concordant clade evidence. The source level is retained in the generated data.
Karyotype: NCBI's reported assembly chromosome count is compared with Tree of Sex female/male 2N. Because many assemblies represent a haploid complement, both 2N and N are considered and the closer expectation is used.
No observed label means no explicit sex-chromosome-style chromosome name was found in the NCBI sequence report. It is missing annotation, not evidence that the organism lacks the expected sex chromosomes.
