In Dawkins theory, we cannot view the act of conception as replication of the [...]
The employment of pre-implentation genetic diagnosis represents an approach to solving problems using science. Design as a discipline is defined as creative and functional method of problem solving. Science in its pure form is often likened to fine art, instigated by a quest for knowledge or understanding.
Applied science (or technology) resembles more applied art (design) [...]
So how does a mutation carrier gets to have a biological child AND avoid being blamed for endowing them with a potentially harmful genetic inheritance? This is where science comes into play and the genetic screening is performed on a selection of embryos instead of after birth.
This screening technique - called pre-implantation genetic diagnosis (PGD) [...]
