TABLE A1.
Expectations of full- and half-sib covariances in the data structure used in Wolf (2003)
| Tube composition
|
|||
|---|---|---|---|
| Covariance | Full-sib pairs | Half-sib pairs | Unrelated pairs |
| FS same |  |
NO | NO |
| FS diff. |  |
 |
 a or  bc
|
| HS same | NO |  |
NO |
| HS diff. |  |
 |
 b or  ac
|
| Unrelated same | NO | NO |  |
| Unrelated diff. | 0 | 0 | 0 |
FS, full sibs; HS, half sibs; same, in the same group; diff., in different groups; NO, this combination does not occur.
a
When the group members of both individuals are full sibs.
b
When the group members of both individuals are half sibs.
c
Only those two covariances provide information to separate the direct and the indirect genetic variance.
