aneuploidy usually reslts from non-disjunction (failure to separate) of homologous chromosomes during meiosis (the creation of gametes). It results in an organism having the wrong number of a certain chromosome.
The two most common forms are monosomy (only one chromosme eg. Turner syndrome) and trisomy (three of a chromosome eg Down and Klinefelter syndrome)
from non-disjunction,
the two chromosomes line up at the equater of a cell as an X, ready to separate, but it doesn't, this reults in one egg/sperm having 0 of a chromosome and another will have 2. If the one with 0 then forms a zygote with a normal egg/sperm the zygote could have only 1 chromosome -from the normal egg/sperm. If the one with 2 forms a zygote the zygote will have 3 of the chromosome, 2 from the mutated gamtete and 1 from the normal gamete.

What is the difference between aneuploid organisms and euploid organisms?
Euploid organisms have a chromosome number that is an exact multiple of the haploid number (Euploid organisms may however, exhibit either an increase or a decrease in the chromosome number). Aneuploid organisms however, have altered genomes - they either lack chromosomes or have extra ones.
What conditions can aneuploidy of sex chromosomes cause?
An example of aneuploid condition is Down syndrome, is due to three copies of choromosome 21 or trisomy 21.
What happens if a cell goes through non-disjunction?
The failure of chromosomes to separate during mitosis results in one gamete that lacks a chromosome and another with 2 chromosomes. Gametes with improper number of chromosomes are called aneuploid gametes. Aneuploid gametes are the most common cause of spontaneous abortion and handfuls of other congenital disorders that varies depending on donors gamete content.

Aneuploid human embryos are least likely to survive, except in cases involving trisomy 21 (Down syndrome). Trisomy 21 is the most common chromosomal disorder compatible with life, although it comes with its own set of health challenges.

A somatic cell that does not contain a multiple of 23 chromosomes is typically referred to as aneuploid. This means it has an abnormal number of chromosomes, which can lead to genetic disorders or abnormalities in development.
