Southern Caracara Karyotype Data: Cytogenomic Analysis of Repetitive DNA

A cytogenomic dataset for the Southern Caracara (Caracara plancus) detailing its highly derived avian karyotype. The data includes results from classical cytogenetics, fluorescence in situ hybridization (FISH), and satellitome analysis, characterizing chromosome organization and repetitive DNA distribution. It was authored by Felipe Lagreca Bitencourt and last updated on May 28, 2026.

Use Cases

• Comparative karyotype analysis based on the described diploid number (2n=88) and chromosome morphology.
• Studying satellite DNA family distribution based on the seven identified satDNA families and their mapping.
• Investigating chromosomal sex dimorphism based on the observed heteromorphism in an autosomal microchromosome pair.
• Analyzing rDNA cluster evolution based on the atypical mapping of 18S rDNA to two microchromosome pairs.

Strengths

• Integrated data from multiple cytogenomic methods (classical cytogenetics, FISH, satellitome analysis).
• Specific karyotypic details are provided, including a diploid number of 2n=88 and the identification of seven satellite DNA families.
• Includes observations of structural variation, such as heteromorphism in a microchromosome pair.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a 1.1 MB DOCX document, which may require parsing to extract structured data.
