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.
Aneuploidy is a type of chromosomal abnormality characterized by an abnormal number of chromosomes in a cell. This can result from the gain or loss of entire chromosomes or parts of chromosomes, leading to genetic disorders and health problems. Examples include Down syndrome (trisomy 21) and Turner syndrome (monosomy X).
It is a chromosomal aberration in which one or more chromosomes are present in extra copies or are deficient in number.
An aneuploid is a cell or organism which has a number of chromosomes which is not a multiple of the haploid number.
An aneuploidy is a condition of being aneuploid, or the state of possessing a number of chromosomes which is not an exact multiple of the haploid number of the organism in question.

What is the difference between aneuploid organisms and euploid organisms?
Aneuploid organisms have an abnormal number of chromosomes due to the gain or loss of individual chromosomes, leading to genetic imbalance. Euploid organisms have a complete set of chromosomes, with the correct number for their species, resulting in a balanced genetic composition.
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?
Non-disjunction occurs when chromosomes fail to separate properly during cell division. This can result in an abnormal number of chromosomes in the daughter cells, leading to conditions such as Down syndrome (trisomy 21). Non-disjunction can disrupt normal cellular function and development.

What is the term for an individual who has an extra copy of one chromosome or is missing a chromosome - Is it something-'ploid'?
Aneuploid - the individual has an extra copy of one chromosome or is missing a chromosome.
Aneuploid human embryos are least likely to survive except those involving?
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 called?
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.
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.
