It is the failure of chromosome pairs to separate properly during cell division.

What happens if a centromere does not break?
Nondisjunction forms and causes Aneoploidy
What happens when an extra chromosome is present?
Down sydrome because of nondisjunction in the chromosomes
What are the three types of nondisjunction?
The three types of nondisjunction are autosomal nondisjunction, sex chromosome nondisjunction, and structural chromosome nondisjunction. Autosomal nondisjunction involves the failure of homologous chromosomes to separate during cell division. Sex chromosome nondisjunction involves the failure of sex chromosomes to separate. Structural chromosome nondisjunction involves the incorrect separation of chromosome parts during cell division.
The faillure of chromosomes to separate during meiosis is called?
The failure of chromosomes to separate during meiosis is called nondisjunction. This can result in an incorrect number of chromosomes in the daughter cells, leading to genetic disorders such as Down syndrome.
How is nondisjunction inherited?
Nondisjunction is an error in cell division that can lead to an abnormal number of chromosomes in a cell. When nondisjunction occurs in germ cells, it can be inherited by offspring, leading to genetic disorders such as Down syndrome. The risk of inheriting nondisjunction increases with parental age.
What happens during meiosis that ultimately results in a defect characterized by the deletion of chromosomes?
Nondisjunction occurs in too many cells or too few cells causing defects
What is it called when chromosomes don't separate correctly during meiosis?
This is known as nondisjunction. It is a mistake that can occur during cell division in meiosis, leading to an incorrect distribution of chromosomes in the resulting gametes.
Is colon cancer nondisjunction?
no
Is fragile x syndrome a result of nondisjunction during meiosis?
yes . it is . nondisjunction is takes place during meiosis.
What happens if nondisjunction occurs during meiosos?
If nondisjunction occurs during meiosis the result could be a wide range of mutations. Most likely it would result in mosaicism meaning there will be a mixture of affected cells and non affected cells.
Where can one find more information about nondisjunction?
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.
What happens when nondisjunction takes place in cell division?
One cell is left without a particular chromosome and another with a duplicated chromosome.Source: An answer on wiki.answers.com that has been modified (by me).
