Detailed explanation-1: -Klinefelter syndrome is a genetic condition that results when a boy is born with an extra copy of the X chromosome. Klinefelter syndrome is a genetic condition affecting males, and it often isn’t diagnosed until adulthood.

Detailed explanation-2: -Most often, boys and men with Klinefelter syndrome have the usual X and Y chromosomes, plus one extra X chromosome, for a total of 47 chromosomes (47, XXY).

Detailed explanation-3: -Usually, a female baby has 2 X chromosomes (XX) and a male has 1 X and 1 Y (XY). But in Klinefelter syndrome, a boy is born with an extra copy of the X chromosome (XXY). The X chromosome is not a “female” chromosome and is present in everyone. The presence of a Y chromosome denotes male sex.

Detailed explanation-4: -Boys typically have one X chromosome and one Y chromosome, or XY, but boys with XXY syndrome have an extra X chromosome, or XXY. Klinefelter syndrome is not caused by anything the parents did or did not do. The disorder is a random error in cell division that happens when a parent’s reproductive cells are being formed.

Detailed explanation-5: -Klinefelter syndrome (KS), also known as 47, XXY, is an aneuploid genetic condition where a male has an additional copy of the X chromosome. The primary features are infertility and small, poorly functioning testicles. Usually, symptoms are subtle and subjects do not realize they are affected.
