Is XXY still a male?
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.
Why are Klinefelter males tall?

What is a Down’s syndrome?
Down syndrome is a condition in which a person has an extra chromosome. Chromosomes are small “packages” of genes in the body. They determine how a baby’s body forms and functions as it grows during pregnancy and after birth. Typically, a baby is born with 46 chromosomes.
Does Klinefelter syndrome affect teeth?
The X chromosome has been linked to enamel thickness as well as the rate of dental development (2, 16, 32, 39, 44-46). Consequently, males affected by KS have larger teeth than males with a normal chromosomal complement (19, 32, 36, 44, 47-49).
