^*When multiple mating occurs, the probability that one male sires each embryo in a litter (see text).

^†The proportion of 10 000 simulated litters for which multiple paternity was successfully inferred at the number of loci indicated.

^‡The proportion of 10 000 simulated litters for which multiple paternity was successfully inferred at one or more loci.
