What occurs during nondisjunction?
If nondisjunction occurs, abnormal numbers of chromosomes may find their way into gametes, and a disorder of chromosome numbers may result.
What effects does nondisjunction have on the body if it occurs during mitosis What problems can an individual have if they have nondisjunction in somatic cells?
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.
Occurs when homologous chromosomes do not separate in meiosis?
Nondisjunction occurs when homologous chromosomes do not seperate. -Amber ^-^
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.
What is it called when chromosomes don't separate correctly during meiosis?
Nondisjunction
What occurs during nondijunction?

What process does non disjunction occur in?
Nondisjunction occurs during anaphase, usually when referring to meiosis, when a tetrad fails to separate.
The faillure of chromosomes to separate during meiosis is called?
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)
If nondisjunction occurs in meiosis II for one chromosome what will be the result at the completion of meiosis?
Some gametes may have an extra copy of some genes.
What is it called when chromosomes don't separate correctly during meiosis?
Nondisjunction
If nondisjunction occurs during meiosis?
It is the failure of chromosome pairs to separate properly during cell division.
