In certain species of salamanders, male-female pairs have multiple mating partners in a breeding season. Which one of the following terminologies accurately describes this mating system?

  • A.monogamy
  • B.polyandry
  • C.polygyny
  • D.polygynandry

Answer: D

The mating system is polygynandry.

In polygynandry both sexes have several mates in a breeding season: each male mates with several females and each female with several males.

Monogamy is one male with one female. Polyandry is one female with several males, and polygyny one male with several females; each describes only one sex having multiple partners, which does not match the question.
