Edward's syndrome karyotype,illustration
Numéro d’image : 12061170
| Karyotype showing the arrangement of chromosomes in a male or female with Edward's syndrome (trisomy-18). Edward's syndrome is caused by a chromosomal anomaly: the 18th set having three rather than the normal two chromosomes. In karyotyping,chromosomes are arranged in numbered pairs according to a standard classification. The male set differs from the female in the sex pair (bottom right); a female would have XX rather than XY. A male Edward's karyotype is written: 47,XY,+18,a female - 47,XX,+18. The normal chromosome count is 46,23 from maternal and 23 from paternal origin. Labelled computer illustration | |
