Nondisjunction occurs when?
homologous chromosomes fail to separate during meiosis
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.
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.
Occurs when homologous chromosomes do not separate in meiosis?
Nondisjunction occurs when homologous chromosomes do not seperate. -Amber ^-^
What is it called when chromosomes don't separate correctly during meiosis?
Nondisjunction
Nondisjunction occurs when?
homologous chromosomes fail to separate during meiosis
Is fragile x syndrome a result of nondisjunction during meiosis?
yes . it is . nondisjunction is takes place during meiosis.
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 during prophase 1 of meiosis?
Mistakes such as nondisjunction can occur during meiosis. This is the result of chromosomes failing to separate equally during either anaphase.
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 process does non disjunction occur in?
Nondisjunction occurs during anaphase, usually when referring to meiosis, when a tetrad fails to separate.
Occurs when homologous chromosomes do not separate in meiosis?
Nondisjunction occurs when homologous chromosomes do not seperate. -Amber ^-^
What occurs during nondijunction?
What occurs during nondisjunction
What is it called when chromosomes don't separate correctly during meiosis?
Nondisjunction
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
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 the failure of chromosome pairs to separate properly during meiosis?
Nondisjunction
