Many biologists adopt the following division of mating systems:

  • monogamous (and sometimes serial monogamous);

  • polygynous;

  • polyandrous;

  • promiscuous/polygynadrous (sometimes distinguished as separate);

  • dispersed.

Say, 80% of males within certain are polygynous (they will get angry if the female will have sex with another male). Yet, 20% are promiscuous. And around the same numbers will apply to females (80% are not interested in multiple partners within the same ovulatory period, but 20% are). Does that species have dispersed mating system or polygynous then? What smallest percent would be needed for this species to count as having dispersed mating system?
