A karyotype of Patau syndrome. What does a Patau syndrome show? Human karyotypes for teaching: (47, XY,+21, Trisomy 21) These karyotypes are from abnormal males. There is a full set of 23 homologous pairs of autosomes, and an X and Y, but an extra chromosome 21. These individuals are also said to have Down syndrome. Karyotype is 47XX+21 or 47XY+21 and the cause is represented by a chromosomal non-disjunction of maternal origin (90%) or a chromosomal non-disjunction of paternal origin (10%). Mosaic trisomy 21 2021-04-13 · Trisomy/tetrasomy 21 mosaicism was found in chorionic villi (semidirect preparation) obtained from a 40 year old pregnant woman.

An extra chromosome (chromosome 21) originates in the development of either the sperm or the egg. When the egg and the sperm unite to form the fertilized egg, three (rather than two) chromosomes 21 are present. Also known as Down syndrome, trisomy 21 is a genetic condition caused by an extra chromosome. Most babies inherit 23 chromosomes from each parent, for a total of 46 chromosomes. Babies with Down syndrome however, end up with three chromosomes at position 21, instead of the usual pair. Other examples of trisomies occur at position 13 and 18.

Trisomy 21 (also known by the karyotype 47,XX,+21 for females and 47,XY,+21 for males) is caused by a failure of the 21st chromosome to separate during egg or sperm development (nondisjunction).
