| Mating typeG | Population frequency | Frequency (m (r) ij ) given r-affected children |
| (2,2) | g 22 | f r 2 g 22 / Kr |
| (2,1) | g 21 | [(f 2 + f 1) / 2]r g 21 / Kr |
| (2,0) | g 20 | f r 1 g 20 / Kr |
| (1,2) | g 12 | [(f 2 + f 1) / 2]r g 12 / Kr |
| (1,1) | g 11 | [(f 2 + 2f 1 + 1) / 4]r g 11 / Kr |
| (1,0) | g 10 | [(f 1 + 1) / 2]r g 10 / Kr |

-
Kr is the population prevalence ofr affected siblings, which equals the sum of all numerators in the third column.
