Within the next few years technology hospitals have these days, parents will be able to pick their childs gender and traits, like the color of their hair and eyes.
How can parents pick their child's traits?
Pre-implantation genetic diagnosis (PGD) is the technology fertility specialists use to have parents be able to pick the sex of their children. Clinics plan to allow parents to be able to choose the children's traits soon. The project is called, "designer babies". Within the next few years specialists are planning to get a 100% garaenty on the sex of the child and an 80% guaranty on the eye color.
My Opinion on Pre-implantation Genetic Diagnosis.
I don't think it's right to be able to pick the gender or traits of children. I disagree mostly with the traits. Not that technology won't be able to make "designer babies" because by the time I am in my twenties fertility specialists will probably going to have these options. I disagree with parents wanting to customize babies the way they want to because it takes away from them being original and unlike anyone else. Parents should accept what they get in their child and like them for them.
