Use this animal consanguinity checker to compare the genetic profiles of a father and a mother using their analysis numbers. The tool evaluates IBS0, IBS1 and IBS2 marker sharing to help estimate relatedness and support breeding decisions.
What this consanguinity checker measures
This tool compares overlapping genetic markers shared between two animals and calculates IBS0, IBS1 and IBS2 values. These indicators help estimate whether the father and mother may be closely related and whether the pairing should be approached with caution.
The tool also attempts to validate sex markers where available, expecting X/Y for the father and X/X for the mother before proceeding with the breeding recommendation.
How to use the tool
Enter the father analysis number.
Enter the mother analysis number.
Submit the form to retrieve both genetic files.
Review the number of compared markers, IBS values and breeding recommendation.
How to interpret the result
A very low IBS0 proportion may suggest a close genetic relationship. Higher marker sharing can indicate that the two animals are too closely related for a recommended breeding. This output should be interpreted together with pedigree review, breed context and professional judgment.
Frequently asked questions
What does this consanguinity checker do?
This tool compares the father and mother analysis numbers, retrieves the associated genetic marker data and calculates IBS0, IBS1 and IBS2 values to estimate relatedness and support breeding decisions.
What information do I need to use the tool?
You need the analysis number of the father and the analysis number of the mother. The tool then attempts to retrieve the genetic data associated with both records.
What do IBS0, IBS1 and IBS2 mean?
IBS0 represents markers with no shared allele, IBS1 represents markers with one shared allele, and IBS2 represents markers with two shared alleles. Together, these values help estimate how closely related two animals may be.
Can this tool replace a pedigree review or expert advice?
No. This tool provides an additional genetic indication and should be used alongside pedigree analysis, breed-specific context and professional breeding judgment.
