Euploidy is the state of a cell or organism having an integral multiple of the monoploid number, possibly excluding the sex-determining chromosomes.
Euploidy, or the euploid number is the normal number of chromosomes within a cell for a species, for example the euploid number of chromosomes in a human cell is 46.

Aneuploidy.
In primates (in contrast to sheep, cattle, and mice), the process of removing the resident nucleus causes molecules associated with the centrosome to be lost as well.

aneuploidy Variation in chromosome number involving one or a small number of chromosomes; commonly involves the gain or loss of a single chromosome.
Aneuploidy
Cells that have extra chromosomes or chromosomes missing are aneuploid. Two types of aneuploidy are discussed below.
Euploidy
The condition of a cell or organism that has one or more complete sets of chromosomes.

The term was proposed by Waldeyer (1888) for the individual threads within a cell nucleus (gk. chroma, colour; soma, body).
euploidy Change in chromosome number from one generation to the next in which there is an addition or deletion of a complete set of chromosomes in the progeny; the most common type is polyploidy.

Definition of aneuploidy :
The condition of a cell or of an organism that has additions or deletions of a small number of whole chromosomes from the expected balanced diploid number of chromosomes.
Aneuploidy -- state of having variant chromosome number (too many or too few). (i.e. Down syndrome, Turner syndrome).
In haploids, in X-linked genes in fly or human males or in dipoloids as a result of aneuploidy or deletion.
