Aneuploidy-the abnormal condition were one or more chromosomes of a normal set of chromosomes are missing or present in more than their usual number of copies. And Euploidy-an entire set of chromosomes is duplicated once or several times. Aneuploidy is the second major category of chromosome mutations in which chromosome number is abnormal.

Euploidy is the condition of having a normal number of structurally normal chromosomes
Aneuploidy. The alternation of chromosome number in a cell by adding or missing particular chromosome or chromosome set or part of a chromosome is called aneuploidy. So, chromosomal number differs from the wild type of the organism due to segregating defects. Aneuploidy and Deletions. Euploidy is the condition of having a normal number of structurally normal chromosomes. Euploid human females have 46 chromosomes (44 autosomes and two X chromosomes), and euploid bulls have 60 chromosomes (58 autosomes plus an X and a Y chromosome). Aneuploidy. Aneuploidy-the abnormal condition were one or more chromosomes of a normal set of chromosomes are missing or present in more than their usual number of copies. Monoploidy-the loss of an entire set of chromosomes. Euploidy-an entire set of chromosomes is duplicated once or several times. Some organisms have more than two sets of chromosomes, and are called polyploidy. Most of the plant species show polyploidity, but rare in higher animals. Aneuploidy is produced by missing or adding particular chromosome or part of a chromosome. The different conditions of aneuploidy are: 1  Nullisomy-the loss of both pairs of homologous chromosomes; individuals are called nullisomics and their chromosomal composition is 2N-2. 2  Monosomy-the loss of a single chromosome; individuals are called monosomics and their chromosomal composition is 2N-1. Aneuploidy Changes in chromosome number can occur by the addition of all or part of a chromosome (aneuploidy), the loss of an entire set of chromosomes (monoploidy) or the gain of one or more complete sets of chromosomes (euploidy). Genetics Index Glossary Aneuploidy and Deletions Euploidy is the condition of having a normal number of structurally normal chromosomes. Euploid human females have 46 chromosomes (44 autosomes and two X chromosomes), and euploid bulls have 60 chromosomes (58 autosomes plus an X and a Y chromosome). Aneuploidy. Aneuploidy is the second major category of chromosome mutations in which chromosome number is abnormal. An aneuploid is an individual organism whose chromosome number differs from the wild type by part of a chromosome set. The most common chromosome abnormalities in miscarriages include: trisomy (three copies of a chromosome) or monosomy (one copy of a chromosome) for chromosomes 13, 15, 16, 18, 21, or 22; triploidy (three copies of all the chromosomes); and abnormalities of the sex chromosomes.
