Aneuploidy (ANN-yoo-PLOY-dee) The condition of having an abnormal number of chromosomes. See Down syndrome.
Antibody A protein produced by the immune system in response to a foreign substance such as a virus or bacterium.
Aneuploid A set of chromosomes which does not contain an exact multiple of haploid sets of chromosomes.
Anticipation The process whereby some genetic diseases get more severe in each successive generation.
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 occurs in humans in the form of triploidy (69,XXX) and tetraploidy (92,XXXX), not to be confused with 47,XXX or 48, XXXX aneuploidy.
Aneuploidy involving the X and Y chromosomes is more common in humans since the results are less devastating than autosomal aneuploidies.
aneuploidy Loss or gain of a chromosome, cells of the organism have one fewer than normal chromosome number, or one extra chromosome, for example, trisomy 21 (Down syndrome).
Aneuploidy -- state of having variant chromosome number (too many or too few). (i.e. Down syndrome, Turner syndrome).
Results in aneuploidy
Usually embryo lethal
Trisomy 21, exception leading to Downs syndrome
Sex chromosomes
Turner syndrome: monosomy X
Klinefelter syndrome: XXY ...
