Table 1.

Missing patterns for one SNP.

Observed/True AA ?? AB BB
AA 1 − αHom αHom 0 0
BB 0 αHom 0 1 − αHom
AB 0 αHet 1 − αHet 0
Probability p1 p2 p3 p4
Count n1 n2 n3 n4

The first row lists the four possible outcomes of the observed genotypes, including the three genotypes and the missingness (??). The first column lists the three true genotypes. Each element in this table is the probability of observing some genotype given the true genotype.
