  • Duchenne muscular dystrophy - normal female, chromosomes have been highlighted by a fluorescent probe for exon 45/47 (note the double yellow band). This disorder is caused by a recessive gene on the X chromosome, so is normally shown only by males, who lack a second X chromosome. The condition starts with difficulty in walking and climbing stairs in early childhood, usually resulting in confinement to a wheelchair by the age of 10, with death from respiratory infection or cardiac failure by about the age of 20.
  • Turner's syndrome karyotype 45,XO. This female lacks the second X chromosome present in the normal karyotype. Symptoms include short stature, neck wbbing, elbow deformity, widely spaced nipples with shield chest, primary amenorrhea, sexual infantilism and sterility. The ovaries are reduced to fibrous streaks. Also known as XO syndrome or ovarian short-stature syndrome.
