The term "monogyne" is often used in biology to describe organisms that have a single queen in their colony, such as certain species of ants. However, there are several synonyms that can be used instead of "monogyne." One alternative term that can be used is "unicolonial," which is used to describe colonies where there is only one breeding population despite the presence of multiple queens. Another synonym for "monogyne" is "monogynous," which is an adjective used to describe organisms that have a single queen. Additionally, the term "monogyny" can be used to describe the state of having only one queen in a colony.
