Gene Absence Ratios Across 31 Non-Human Primate Species

A 2026 dataset from figshare by Xiao Liang analyzes gene absence patterns across 31 non-human primate species. It calculates large and small clade absent ratios for gene sets present in at least one species. The data is provided in an XLS file under a CC-BY-4.0 license.

Use Cases

• Calculate gene absence ratios based on the defined large and small clades.
• Compare patterns of gene loss across different primate lineages.
• Identify gene sets with high absence rates in specific primate clades.
• Validate evolutionary models of gene content change using empirical absence data.

Strengths

• Focuses on a specific set of 31 non-human primate species.
• Defines clear metrics for gene absence analysis (N, P, Q ratios).
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• The dataset is very small at 5.5 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
