Non-disjunction can result in a number of different conditions, including Down syndrome, Klinefelter Syndrome, Turner's Syndrome, Super Males, Triple X syndrome or Edward's Syndrome.
Various kinds of genetic disorders, as the embryo will end up with two copies or zero copies of a gene.
Nondisjuction causes the separation of chromosomes; which causes types of mutations to occur, or even allow the individual to be prone to disease.
Autosomal nondisjunction is the most prolific cause of trisomy 21, or down syndrome, a defect that usually occurs during meiosis 1, but can occur during 2 as well.

Its called disconjunction. Sometimes it is so bad that they have a miscarriage or the following happens:Trisomy (extra chromosomeso have 47 chromosomes instead of 46)Down's syndrome (andextra number 21 chromosome)Klinefelter's syndrome (males with an extra X chromosome...XXY)
Nondisjunction
no
yes . it is . nondisjunction is takes place during meiosis.
Nondisjunction is the addition or deletion of an entire chromosome. The result could be autism or downs syndrome
Nondisjunction is the failure of a homolog to separate during meiosis causing trisomy (an extra chromosome) or monosomy (a missing chromosome), it can be harmful because it is a mutation that can cause many devastating disease, for example nondisjunction of the 21st chromosome causes down syndrome, another example of nondisjunction being harmful, is nondisjunction of the sex chromosomes, causing Turner's or Klinefelter's syndrome two very devastating diseases.
One can find more information about nondisjunction on Wikipedia or Biology Online. Both of these website have lots of information. One can see diagrams relating to nondisjunction on Google Images.
Nondisjunction is a very bad thing and cells and can lead to lying of the cell.
The significance of crossing over and nondisjunction is that it increases biodiversity. This is important for the environment and food chains.
