What is DNA Testing?
DNA Testing: DNA (deoxyribonucleic acid) is the genetic blueprint that determines a person’s biological characteristics. DNA is located in the cell of the human body. Upon conception, a child inherits one half of its DNA from its mother and one half from its father. This unique combination of DNA will match that of the biological parents of the child. For the test to take place, cheek cells are removed with a swab from the mouth of the mother, the child and the alleged father. In the laboratory, these cells are removed from the swab and tested. When a child’s DNA does not match that of the alleged father, he is excluded 100% as the biological father of the child. When the child’s DNA does match that of the alleged father, this means that the alleged father “could be” the father of the child, but it does not prove that he “is” the only possible father, since related individuals, such as brothers, can share DNA characteristics. However, a DNA test can prove a probability of 99% or greater for paternity.
Westwick says even otherwise reputable music schools are getting in on the revenue-generating game of DNA testing. ”Magic Fidler is a company running children’s music classes with a sideline in DNA testing to determine musical ability,” she writes. The Magic Fiddler website boasts that “for $2,000 the scientific results can pinpoint your child’s strengths and weaknesses in 40 areas, including IQ, EQ, memory as well as artistic and athletic abilities.” An extra $800 will get you “the DNA Test plus 12 weekly music classes.”
None of these tests are based on actual science, as the LA Times points out. “Even well-respected researchers in the field of genomics are struggling to come up with clear, verified links between complicated traits and specific genes.” Westwick thinks, however, that “the genomics juggernaut is on a roll, bringing with it more robust links between personality traits and DNA sequence.” She wonders, ”When predictive testing finally comes of age, should we allow children to be tested?” Would you?
