match, i.e. 10/10, 8/8 or 6/6

• The locus match probability is the relative probability that this locus is a match in the 1 mismatch case.

mismatch, i.e. 9/10, 7/8 or 5/6

• The locus match probability is the relative probability that this locus is a match in the 2 mismatch case.
  
  

So this probability provides information on which locus the next mismatch will occur.

match, i.e. 10/10, 8/8 or 6/6

• The locus match probability is the probability that this locus is a match no matter the amount of overall mismatches.

match

• When p1 = 0 (division by zero, not defined).

mismatch

• When p2 = 0 (division by zero, not defined).
• When a donor/CBU already has at least two known mismatches. As Hap-E only calculates match probabilities for up to 2 mismatches, Hap-E also is not able to calculate the locus-specific match probabilities in case of the third mismatch.
  
  

inexplicable donors

• When a donor's phenotype cannot be explained by the haplotype frequency sets used for probabilistic matching. It is therefore impossible to calculate match probabilities both at the considered loci in total and per-locus.
