1. Adjective:
   • Having a chromosome number that is not an exact multiple of the haploid number: In genetics, this describes a cell or organism where the total number of chromosomes is not a simple multiple (e.g., 2n, 3n) of the basic haploid set (n). This condition involves an abnormal number of individual chromosomes.

Examples of Usage

• Adjective:
  • The fetus was diagnosed with an aneuploid condition.
  • Aneuploid cells are often found in cancerous tumors.

Synonyms

• Chromosomally abnormal: Having an irregular chromosome number or structure.
• Numerical chromosomal aberration: A more technical term for a change in chromosome number.
