Consistent Paternity Skew through Ontogeny in Peron's Tree Frog (Litoria peronii)
BACKGROUND A large number of studies in postcopulatory sexual selection use paternity success as a proxy for fertilization success. However, selective mortality during embryonic development can lead to skews in paternity in situations of polyandry and sperm competition. Thus, when assessment of paternity fails to incorporate mortality skews during early ontogeny, this may interfere with correct...
متن کاملMales with high genetic similarity to females sire more offspring in sperm competition in Peron's tree frog Litoria peronii.
Recent work has confirmed that genetic compatibility among mates can be an important determinant of siring success in sperm competition experiments and in free-ranging populations. Most of this work points towards mate choice of less related mates. However, there may also be the potential for mate choice for intermediate or even genetically similar mates to prevent outbreeding depression or hyb...

متن کاملConsistent male-male paternity differences across female genotypes.
In a recent paper, we demonstrated that male-female genetic relatedness determines male probability of paternity in experimental sperm competition in the Peron's tree frog (Litoria peronii), with a more closely related male outcompeting his rival. Here, we test the hypothesis that a male-male difference in siring success with one female significantly predicts the corresponding difference in sir...
