48,XXYY syndrome is a condition related to the X and Y chromosomes (the sex chromosomes). People normally have 46 chromosomes in each cell.Two of the 46 chromosomes, known as X and Y, are called sex chromosomes because they help determine whether a person will develop male or female sex characteristics.
Klinefelter syndrome (KS), also known as 47,XXY, is a chromosome anomaly where a male has an extra X chromosome. [10] These complications commonly include infertility and small, poorly functioning testicles (if present).
In humans with more than one X chromosome, the number of Barr bodies visible at interphase is always one fewer than the total number of X chromosomes. For example, people with Klinefelter syndrome (47, XXY) have a single Barr body, and people with a 47, XXX karyotype have two Barr bodies.

Due to its exceptional rarity, little is known about XXXYY syndrome. There are no unbiased descriptions of the disorder; all living XXXYY males reported in the medical literature were diagnosed after birth due to symptoms, and it is unknown if there are milder cases that have not come to diagnostic attention.
[31] [32] Complete androgen insensitivity syndrome results in a genetic male having a vagina, clitoris, and breasts which are capable of breastfeeding. However, they will not have ovaries or a uterus. Because they do not have ovaries or sufficiently developed testicles, people with complete androgen insensitivity syndrome are infertile. [33]
XYYYY syndrome, also known as 49,XYYYY, is an exceptionally rare chromosomal disorder in which a male human has three additional copies of the Y chromosome. Only seven non- mosaic cases of the disorder have ever been recorded in the medical literature, as well as five mosaic cases, of which two had more 48,XYYY than 49,XYYYY cells. [ 1 ]
English: *en:XXY syndrome. Blue circles are male cells. Blue bars are Y-chromosomes; Pink circles are female cells. Pink bars are X-chromosomes. MI corresponds to the first stage in meiosis; MII corresponds to the second stage in meiosis; Problems with cell division in the M II-stage in the female results in a cell with 2 X-chromosomes.
