PEDIGREE ANALYSIS
PI BIG
Calculated from accepted public parentage. This is a pedigree model, not a DNA measurement.
Pedigree-based COI
Estimate unavailable
No accepted ancestors are recorded for this dog. Source-reported ancestry is not automatically included in this calculation.
The full recorded pedigree must fit within 1024 records.
Calculation assumptions
Unknown parents and distinct boundary founders are assumed unrelated. Founder inbreeding is assumed zero.
Boundary founders have no recorded parents in this calculation.
Missing ancestry can underestimate this coefficient; incorrect ancestry can bias it in either direction.
