Aneuploidy vs. Polyploidy

Aneuploidynoun

(genetics) The condition of being aneuploid; the state of possessing a chromosome number that is not an exact multiple of the haploid number of the organism in question.

Aneuploidynoun

an abnormality involving a chromosome number that is not an exact multiple of the haploid number (one chromosome set is incomplete)

Aneuploidy

Aneuploidy is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. It does not include a difference of one or more complete sets of chromosomes.

Polyploidynoun

(genetics) The condition of being polyploid or the process of becoming polyploid

Polyploidynoun

the condition of being polyploid

Polyploidy

Polyploidy is a condition in which the cells of an organism have more than two paired (homologous) sets of chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes—one set inherited from each parent.
