Mitochondrial Haplogroup Phylogenetic Trees for Indian and South Asian Populations

144 published mitochondrial sequences from Indian, South Asian, and global populations are integrated into phylogenetic trees constructed via Maximum Parsimony. Each node includes a time to TMRCA with a 95% confidence interval, calculated using Rho statistics. The dataset, authored by Anjana Welikala and updated in 2026, is a 116.7 KB Excel file.

Use Cases

• Compare mitochondrial haplogroup divergence times based on TMRCA estimates with confidence intervals.
• Analyze phylogenetic relationships between Sinhalese, Vedda, and other South Asian populations based on colored branch annotations.
• Validate Maximum Parsimony tree construction methods using published reference sequences.
• Study genetic diversity and population history within Indian subcontinental groups.

Strengths

• Includes 144 published mitochondrial sequences, providing a substantial reference set.
• Trees contain time to TMRCA estimates with 95% confidence intervals for each node.
• Specific populations (Sinhalese, Vedda) are visually annotated, aiding comparative analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the selected published sequences.
