Table 2.
Illustration of the experimental design. Two pairs of genetic sisters (here A1–A2 and B1–B2) and two pairs of foster sisters (here C1–C2 and D1–D2) were tested with eight sets of males. Between trials, they were housed in duplets of two females per cage (C). We compared the agreement between genetic sisters (GS) and foster sisters (FS) to the agreement between unrelated females that did not share the same foster parents (U).
