What happens when a male has xxy sex chromosomes?
Nondisjunction will occur . Yep
What is nondisjunction and what does it occur?
Nondisjunction can occur during Anaphase in mitosis, or either Anaphase I or II in meiosis. This is the step of each aformentioned process when the chromosomes are separated into different regions within the dividing cell, so they can be segregated further by cytokenesis.
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)
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 phase does nondisjunction of chromosomes resulting in aneuploidy occur?
anaphase
Does Triple X syndrome occur because of nondisjunction?
yes
What happens when a male has xxy sex chromosomes?
Nondisjunction will occur . Yep
In Jacob syndrome did the nondisjunction occur in the mother or father?
Jacob syndrome, 49XYY, has to occur as a result of nondisjunction in the father. The Jacob Syndrome male would have received the X chromosome from his mother, and both Y chromosomes from the father (since the Y chromosomes can not possibly have come from the mother). Jacob Syndrome can be the result of nondisjunction in meiosis.
What is nondisjunction and what does it occur?
Nondisjunction can occur during Anaphase in mitosis, or either Anaphase I or II in meiosis. This is the step of each aformentioned process when the chromosomes are separated into different regions within the dividing cell, so they can be segregated further by cytokenesis.
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 process does non disjunction occur in?
Nondisjunction occurs during anaphase, usually when referring to meiosis, when a tetrad fails to separate.

What is it called when chromosomes don't separate correctly during meiosis?
Nondisjunction
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.
Is colon cancer nondisjunction?
no
Is fragile x syndrome a result of nondisjunction during meiosis?
yes . it is . nondisjunction is takes place during meiosis.
