Figure 3 . A histogram displaying expected values of relatedness
(R xy) among groups of adult Yellowstone Cutthroat
trout; (A ) adults assigned progeny via parentage analysis, and
(B ) adults without any assigned progeny. Vertical dotted lines
correspond to the observed mean levels of relatedness among individuals
within a group (Obs mean) and mean expected values of relatedness (Exp
mean) generated by randomly shuffling individuals between groups are
listed in the upper right of each graph. P-values represent the number
of simulations out of the total number ran that were less than or equal
to our observed value.
