Summary
Thirteen microsatellite markers effectively identified parentage in JIRONG Rabbits. This genetic analysis provides high confidence for parentage testing, crucial for rabbit breeding programs.
Area of Science:
- Animal genetics
- Molecular biology
- Forensic science
Context:
- Microsatellite markers are valuable tools for genetic analysis.
- Parentage testing is essential for selective breeding and genetic management in livestock.
- JIRONG Rabbits represent a specific population for genetic studies.
Purpose:
- To evaluate the efficacy of 13 microsatellite markers for parentage testing in JIRONG Rabbits.
- To determine the genetic parameters such as allele number, heterozygosity, and polymorphism information content.
- To assess the exclusion probability and confidence levels for parentage verification.
Summary:
- Thirteen microsatellite loci (Sat2-Sat16, Sol03, Sol08, Sol28, Sol30) were successfully amplified and analyzed in 30 JIRONG Rabbits.
- The markers exhibited an average of 3.46 alleles, 0.578 mean heterozygosity, and 0.531 polymorphism information content.
- High combined exclusion probabilities (PE1=0.935, PE2=0.999) were achieved, enabling successful identification of paternal lines with known maternal data.
Impact:
- Establishes a reliable microsatellite-based method for JIRONG Rabbit parentage verification.
- Contributes to improved genetic management and breeding strategies in rabbit populations.
- Demonstrates the utility of specific microsatellite markers in animal forensics and population genetics.
