Chromosome differences
The nucleus of a human cell usually contains 46 chromosomes, comrpising 22 pairs of autosomes, plus two allosomes (sex chromosomes). The two allosomes are usually X and Y for a man, or X and X for a woman. Some other combinations are:
- 45,X – a female with one X chromosome missing, also known as Turner syndrome
- 47,XYY – a male with an extra Y chromosome
- 47,XXY – a male with an extra X chromosome, also known as Klinefelter syndrome
- 47,XXX – a female with an extra X chromosome
