- When does are bred on multiple heat cycles, it may appear that superfetation has occurred due to fetal sizes and maturity differences.
- The authors argue that conception during pregnancy, known as superfetation, benefits female reproductive fitness by reducing the risk of infanticide, extending the female's window of opportunity for conception, and increasing the genetic diversity of the litter.
- The researchers believe the combination of embryonic diapause and superfetation may benefit females, regardless of their social system, by enabling cryptic polyandry - mating with more than one male.
