It is a wise father that knows his own child, but today a man can boost his paternal (fatherly) wisdom — or at least confirm that he’s the kid’s dad. All he needs to do is shell out $30 for a paternity testing kit (PTK) at his local drugstore — and another $120 to get the results.
More than 60,000 people have purchased the PTKs since they first become available without prescriptions last year, according to Doug Fogg, chief operating officer of Identigene, which makes the over-the-counter kits. More than two dozen companies sell DNA tests directly to the public, ranging in price from a few hundred dollars to more than $2,500.
Among the most popular: paternity and kinship testing, which adopted children can use to find their biological relatives and families can use to track down kids put up for adoption. DNA testing is also the latest rage among many passionate genealogists — and supports businesses that offer to search for a family’s geographic roots.
Most tests require collecting cells by swabbing saliva in the mouth and sending it to the company for testing. All tests require a potential candidate with whom to compare DNA.But some observers are skeptical. "There is a kind of false precision being hawked by people claiming they are doing ancestry testing," says Troy Duster, a New York University sociologist. He notes that each individual has many ancestors — numbering in the hundreds just a few centuries back. Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a father’s line or mitochondrial DNA, which is passed down only from mothers. This DNA can reveal genetic information about only one or two ancestors, even though, for example, just three generations back people also have six other great-grandparents or, four generations back, 14 other great-great-grandparents.
Critics also argue that commercial genetic testing is only as good as the reference collections to which a sample is compared. Databases used by some companies don’t rely on data collected systematically but rather lump together information from different research projects. This means that a DNA database may have a lot of data from some regions and not others, so a person’s test results may differ depending on the company that processes the results. In addition, the computer programs a company uses to estimate relationships may be patented and not subject to peer review or outside evaluation.
PTK is used to________.
选项
A、locate one’s birth place
B、promote genetic research
C、identify parent-child kinship
D、choose children for adoption
答案
C
解析
事实细节题。从文中第三段可以看到“被收养的孩子可以通过亲子鉴定找到他具有血缘关系的亲属”。A选项比较具有迷惑性,从第三段后半句我们可以看出“.PTK最近惹怒了很多谱系学家,他们支持用PTK来探寻一个家族的祖籍”。可以看出PTK没有主要被用来寻找一个人的出生地。选项B、D文中未提及。
