Sea Turtle Hybridization Case Study Verified by Mitochondrial and Nuclear Sequences

A 2026 case study describes a juvenile sea turtle specimen found near Cancun, Mexico, exhibiting mixed morphological features of Eretmochelys imbricata and Chelonia mydas. Genetic analysis of one mitochondrial and five nuclear loci confirmed it as a first-generation hybrid. The dataset, authored by Iván G. Hernández-Ávila, is a 164.7 KB document shared under a CC-BY-4.0 license.

Use Cases

• Study hybridization events in marine turtles based on genetic loci analysis described.
• Compare mitochondrial and nuclear DNA sequences for species identification based on the methods.
• Analyze morphological and genetic correlations in hybrid specimens based on the case study findings.

Strengths

• Genetic analysis includes one mitochondrial and five nuclear loci (R35, BDNF, CMOS, RAG1, RAG2).
• Includes data from 15 reference specimens (7 E. imbricata, 8 C. mydas) for comparison.
• Case study provides specific geographic context (NW Caribbean, Yucatan Peninsula).

Limitations

• Dataset is a single 164.7 KB document, indicating a very limited scope.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• Data may reflect geographic bias inherent to the single specimen case study.
