Genetic Modification?

Inheritable Genetic Modification is defined as the ability to change the genes passed on from generation to future generations. This means that all the genetic characteristicts transmitted from parent to offspring  can be modified to have added traits that correspond to transferred genes that are eventually passed on. Genetic changes would occur in the gametes (egg, and sperm)  or in the early embryos. The modifided genes would not only appear in the person who was developed from the embryo or gamete but also in their succeding offspring. There are many pros and cons to inheritable genetic modification (designer babies).
CONS

• The process has a high risk and if the embryo is not treated carefully in can accidentally cease. 
• Technology for this process is not 100% safe yet. 
• Parents may use this for superficial purposes, seeking for the "perfect child".
• It would create a gap in society; it could cause there to be "classes" among the designer babies and regular babies. 
• Geneticists aren't fully able to evaluate every single genes and that can lead to mistakes being made. 

PROS

• It can potentially increase human life span up to 30 years. 
• It can also prevent genetic diseases such as Alzheimer's, Huntington's Disease, and many others. 
• Parents would be allowed to provide a healthier life.
• Eliminates mitochondrial disorders.
• It also installs a better understanding go genetics for genealogists and biologists.
