Chromosomes fails to split during mitosis. That is non-dis junction. Due to that, different proteins are produced. (because the DNA is messed up and so is the amino acid chain. That is why different protein is produced that needed.) That causes serious problems. Not all mutations are harmful.
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.
Nondisjunction
Nondisjunction will occur . Yep
Nondisjunction occurs during the Anaphase stage of Meiosis. In this stage, the sister chromosomes move to opposite sides of the cell. However, in Nondisjunction one or more set(S) of chromosomes move to the same side of the cell.
Nondisjunction occurs during anaphase, usually when referring to meiosis, when a tetrad fails to separate.
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 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 occurs during nondisjunction
Nondisjunction
Nondisjunction
If nondisjunction occurs, abnormal numbers of chromosomes may find their way into gametes, and a disorder of chromosome numbers may result.
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.
Nondisjunction occurs when homologous chromosomes do not seperate. -Amber ^-^
homologous chromosomes fail to separate during meiosis
Nondisjunction forms and causes Aneoploidy
Nondisjunction occurs in too many cells or too few cells causing defects
Nondisjunction will occur . Yep
Down sydrome because of nondisjunction in the chromosomes
