monoploid

This term is a specialized technical descriptor used primarily in genetics and cytology. It describes a state of ploidy where only one complete set of chromosomes is present, distinguishing it from diploid (two sets) or polyploid (more than two sets) states. It is most frequently encountered in academic research, botanical studies, and medical genetics.

When used as a noun, the term refers to the specific entity—such as a cell or an organism—that exhibits this chromosomal state. In practical application, it is often used to describe induced mutants in plants created for the purpose of mapping genes or studying the effects of removing redundant genetic material.
