Uni-sexual refers to organisms that have only one type of sexual organ or only one reproductive structure. Synonyms for this term may include mono-sexual, uniparental, and hermaphroditic. Mono-sexual organisms only possess sexual organs of one gender, such as male or female. Uniparental organisms reproduce using only one parent, such as through asexual reproduction. Hermaphroditic organisms possess both male and female reproductive structures, allowing them to reproduce with themselves or with other hermaphrodites. These synonyms can be used interchangeably depending on the context and specific traits of the organism in question.
