For example, a missing X chromosome results in a condition known as Turner’s syndrome, which affects females only. Approximately one in every 3,000 girls is born with this syndrome. The main features include shortness of stature, absence or very retarded development of secondary sexual characteristics. These people are unmistakably female in appearance and identity, although full female sexual characteristics never develop. Menstruation can be induced by oestrogen drugs, but sufferers continue to be infertile.
