highly significantP = 0.009
We found a negative and a highly significant relationship between adult female and offspring relatedness within groups ( R 2 = 0.59; F 1,8 = 11.71; P = 0.009; Fig. 4 ); that is, for social groups in which adult females were more closely related to each other, offspring exhibited relatively lower relatedness values (i.e ., sired by multiple males).
