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.
Does photosynthesis occur in lotus leaves?
yes happens in all plants
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)
What happens when a male has xxy sex chromosomes?
Nondisjunction will occur . Yep
What phase does nondisjunction of chromosomes resulting in aneuploidy occur?
anaphase
Does Triple X syndrome occur because of nondisjunction?
yes
What happens if a centromere does not break?
Nondisjunction forms and causes Aneoploidy
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 happens when an extra chromosome is present?
Down sydrome because of nondisjunction in the chromosomes
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.
Nondisjunction happens in?
It is the failure of chromosome pairs to separate properly during cell division.
What process does non disjunction occur in?
Nondisjunction occurs during anaphase, usually when referring to meiosis, when a tetrad fails to separate.
What stage of cell division would down's syndrome occur?
Down syndrome (trisomy 21) occurs when a gamete carrying an extra copy of chromosome 21 is involved in a fertilization event.The gamete (whether sperm or oocyte) has an extra copy of chromosome 21 because of something called NONDISJUNCTION. This happens when a chromosome gets pulled to the wrong daughter cell.This can happen either in meiosis I or meiosis II.If nondisjunction happens in meiosis I, 2 gametes will be n+1 (have the extra copy of 21) and the other 2 gametes will be n-1 (will have NO copy of 21)If nondisjunction happens in meiosis II, 2 gametes will be normal, one will be n+1 and one will be n-1.
