Klinefelter's Syndrome

Normally, humans have 46 chromosomes, namely 22 pairs of autosomes and 1 pair of sex chromosomes. In females, both sex chromosomes are X chromosomes (XX), while in males, there is one X and one Y chromosome (XY). Klinefelter's Syndrome (KS) is a sex chromosomal disorder like Turner's syndrome, while KS individuals have an extra X chromosome making the total number of chromosome or 47 chromosomes, a person with Turner's lacks a X chromosome and has a total of 45 chromosomes.
