Bildnummer 12061169
| Karyotype showing the arrangement of chromosomes in a female with Down's syndrome (trisomy-21),the most common diagnosable cause of mental handicap,computer illustration. Down's syndrome is caused by a chromosomal anomaly: the 21st set having three rather than the normal two chromosomes. In karyotyping,chromosomes are arranged in numbered pairs according to a standard classification. The female set differs from the male in the sex pair (bottom right); a male would have XY rather than XX. A female Down's karyotype is written: 47,XX,+21. The normal chromosome count is 46,23 from maternal and 23 from paternal origin | |
