Polygynandry

Polygynandry is when both males and females have multiple mating partners during a breeding season.Davies N.B; Krebs J.R; West S.A. 2012. An introduction to behavioural ecology: Mating systems, Chapter 7, 9, 179-222, 254-281. In sexually reproducing diploid animals, different mating strategies are employed by males and females, because the cost of gamete production is lower for males than it is for females.Halley M.R; Heckscher C.M. & Kalavacharla V. 2016. Multi-generational kinship, multiple mating, and flexible modes of parental care in a breeding population of the veery (Catharus fuscescens), a trans-hemispheric migratory songbird. PLosONE 11(6).
