To discover if a sperm or egg cell might have a genetic defect scientists can test the mother or father's blood to see the possibility of an inherited genetic defect and hopefully change or fix the DNA if there is a defect. Altering genetics can result in positive effects such as the diminishing of diseases and people with longer healthier lives. There are downsides to altering genetics too, longer lives means and fewer diseases means overpopulation and the struggles that come with that Scientists are also unsure of the long term effects that changing genetics could have. Scientists should not be allowed to genetically engineer offspring because of overpopulation, the uncertainty of long-term effects, and the absence of the needed genetic mutations could greatly affect humans as a …show more content…
one site claimed that a child that was genetically engineered was born in 1997, making him or her 18 or 19 years old now. If this is true there is still research to be done including how the genetically engineered child's future offspring may be affected or if they will be affected at all. In the movie Gattaca each embryo had to be genetically modified, therefore the "perfect genetics" are not able to be passed on to each generation naturally. Engineering genetics also decreases the chance of mutations. Genetic mutations are often associated with negative effects. However, mutations in the genetic code can be a positive thing. An article on the Tech Museum of Innovation website explains “Over time, genetic mutations create genetic diversity, which keeps populations healthy. Many mutations have no effect at all.” Without genetic mutations would humans might not be as generally healthy. Should the public be allowed to genetically modify their offspring despite the unknown and known
