This experiment tested the aggression levels of females when given a choice between a clonal sister (VI/17 Río Purificación, Nuevo Padilla, MX) and non-sister (Comal Spring, TX (7a), (Relatedness coefficient = -0.057; average±SE). Females received (blue) significantly more bites (A. given: F(1) = 2.305, p = 0.138; received: F(1) = 6.668, p = 0.014) and spent significantly more time performing (given = red) aggressive behaviors (B. given: F(1) = 5.866, p = 0.021; received: F(1) = 4.001, p = 0.054) towards non-sisters when compared to clonal sisters. There was no significant difference in performing tail beats (A. given: F(1) = 2.125, p = 0.154; received: F(1) = 2.125, p = 0.154).
