Abstract

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 siring success with
another female. With male sperm concentration
held constant, and the proportion of viable
sperm controlled statistically, the male–male
difference in siring success with one female
strongly predicted the corresponding difference
in siring success with another female, and
alone explained more than 62 per cent of the
variance in male–male siring differences. This
study demonstrates that male siring success is
primarily dictated by among-male differences in
innate siring success with less influence of male–
female relatedness.
