What is an example of a disorder associated with an error in the number of chromosomes present?
Down syndrome (trisomy 21) is a disorder associated with an error in the number of chromosomes present. Other examples of disorders associated with an error in the number of chromosomes are Trisomy 18 (Edwards Syndrome), Trisomy 13 (Patau Syndrome), Triple X syndrome, and Klinefelter Syndrome.

How do chromosome mutations affect an individual?
Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome. Unlike a gene mutation which alters a single gene or larger segment of DNA on a chromosome, chromosome mutations change and impact the entire chromosome.
What are some diseases non-disjunction causes?
No " following, but a condition such as trisomy 21, Downs syndrome, is caused by nondisjuction. The chromosomes fail to separate properly and one child is left with an extra chromosome number 21. The potetial other children that could have been born of this nondijuction event, those with only one chromosome 21, are not viable.
How many copies of Chromosome 21 are there in someone who has Down syndrome?
3 Pairs of Chromosome 21There are 47 chromosomes in someone with Down syndrome (most people have 46); the 21st pair has an extra chromosome. Down syndrome is also known as "Trisomy 21" - a reference to the fact that someone with Down syndrome has 3 pairs of chromosomes 21.
Which disorder is characterized by an abnormal number of autosomes?

What are traits about chromosome number 8?
Chromosome number 8 is a medium-sized chromosome in humans, containing around 800-900 genes. It is involved in various genetic disorders, such as Wolf-Hirschhorn syndrome and Langer-Giedion syndrome. Chromosome 8 also plays a role in cancer development, as mutations in genes located on this chromosome can lead to uncontrolled cell growth.
