Table 1.
Coefficients of relatedness for a haplodiploid female for various female and male relatives
| Full sibling | Half sibling | Own offspring | Offspring of full sister | Offspring of half sister | Mother related by rqq, father unrelated | ||
| Females | average | 3/4 | 1/4 | 1/2 | 3/8 | 1/8 | rqq/4 |
| patrigenic | 1 | 0 | 1/2 | 1/2 | 0 | 0 | |
| matrigenic | 1/2 | 1/2 | 1/2 | 1/4 | 1/4 | rqq/2 | |
| Males | average | - | 1/2 | 1 | 3/4 | 1/4 | rqq/2 |
| patrigenic | - | 0 | 1 | 1 | 0 | 0 | |
| matrigenic | - | 1 | 1 | 1/2 | 1/2 | rqq |
These are regression coefficients that do not include reproductive value differences between males and females. The last column is for relationships like cousins, with mothers related by rqq = 3/4 and fathers unrelated.
