or roughly 1.5 to 2 percent of the human genome. In a condition called trisomy 21, usually, three copies of chromosome 21 are produced in each cell, resulting in what is commonly known asDown syndrome. (This is very commonly written incorrectly as "Down's syndrome.") Less commonly, this ...
Trisomy 21 results when a baby has three rather than the typical two copies of chromosome 21 in all of his or her cells. Gastrointestinal abnormalities are also common among these individuals. For example, obstruction of the esophagus or duodenum is fairly common and some cases are serious enoug...
Triple X syndrome (also called trisomy X syndrome, XXX syndrome, or 47,XXX) is a rare genetic condition where females inherit an extra X chromosome. For some females with triple X syndrome, the third X chromosome can be found in every cell in their body. For others, it is only found i...

How an NT screening is done An NT is a special type of ultrasound done using a very sensitive but safe machine. A sonographer will apply a transducer (wand) to the outside of your stomach to measure your baby from crown to rump and check that the fetal age is accurate. Then he or ...
Likewise, single men and same-sex male partners often resort to surrogacy to have a baby, as it is the only way for them to have a genetic child using their reproductive cells. In these cases, surrogacy is required just because human males do not have the anatomy needed for natural embryo...

One of the first explicit instructions in medical literature on cesarean technique dates from about 1480 CE from ...
The NT scan isn't invasive, but as a screening test, it's also not conclusive. Diagnostic testing such as CVS or amniocentesis is necessary to confirm a positive result. Video In addition to testing for Down syndrome (trisomy 21), the NT scan will also screen for: Advertisement | page ...
