Yes. That chromosome disjunction event is called Kleinfelter's syndrome.

What can an extra chromosome do?
Yes, it is possible to have XXX, XXY, or XYY sex chromosomes.
What are the sex chromosomes of male human being?
Normal male humans have the sex chromosomes XY. The presence of the Y chromosome determines sex in humans - so a person with XXY will be male.
How is sex determined in a person with a chromosomal disorder involving the sex chromosomes?
if you have a Y chromosome, you are male.if only a X chromosome then you are a female.Ex.XY, XXY, XYY, XXXXY, etc. - MALEX, XX, XXX, XXXX, etc. - FEMALE
What is special about sex chromosomes?
Sex chromosomes can be either x or y: x+x=girl, x+y= boy. yyx and xxy occur sometimes but these children have developmental problems and are infertile. xxy is called Klinefelter's syndrome. Because there are some alleles attached to the x chromosome that cannot be paired with a y chromosome, there are some conditions that a male can get but are rare for a female. Colour blindness and haemophilia are conditions that are carried on the x chromosome, females have two x chromosomes so the condition does not manifest itself whereas males have one x chromosome so that chromosome can dominate.
What would a male with the sex chromosomes xxy have?
Kleinfelter's syndrome.
What can an extra chromosome do?
Yes, it is possible to have XXX, XXY, or XYY sex chromosomes.
What is a baby's gender if he or she has XXY sex chromosomes?
Male - in humans the sex is determined by the presence of a Y chromosome. In other animals sex can be determined by the ratio of sex chromosomes, or the total number of chromosomes.
What are the sex chromosomes of male human being?
Normal male humans have the sex chromosomes XY. The presence of the Y chromosome determines sex in humans - so a person with XXY will be male.
The sex chromosome composition of a person with klinefelter syndrome is?
XXY. Klinefelter is caused when the X chromosomes of the mother fail to split, or an XY sperm reaches an X egg, resulting in a mostly male child.

What causes disorders such as klinefelter syndrome and turner syndrome?
Klinefelter syndrome is a chromosomal condition that only affects males and is characterized by a male having an additional X chromosome (XXY) in cells. This chromosome abnormality occurs when there is an error in cell division, resulting in an extra copy of the X chromosome.
Is Klinefelter Syndrome sex-linked or autosomal?
Klinefelter Syndrome is sex-linked, because it is a genetic defect that results in a male having an extra X chromosome.
How is x chromosome involved with sex determination?
In humans, normal females have XX chromosomes, and males have XY. It is the presence of a Y chromosome that makes an individual a male, not the ratio of X to Y or the presence of only one X. Therefore someone with XXY would be male.
Trisomy 21 Down syndrome xxy kleinfelter syndrome and xo turner syndrome are all caused by?
Nondisjunction -Trisomy 21(Down Syndrome) means there are 3 chromosomes on the 21st pair of chromosomes. -Kleinfelters (XXY) means there is an extra chromosome on the 23rd pair(where the sex chromosomes lie). -Turner Syndrome(XO) On the 23rd pair, there is no Y or second X chromosome. The female can survive with this.
What would a male with the sex chromosomes xxy have?
Kleinfelter's syndrome.
What is the difference between sex chromosome an autosomal chromosome?
the autosome do not control the sex organs . but the sex chromosome control the sex organs
