### Let's say option B is standard pre-implantation genetic testing for
aneuploidy, which helps avoid giving your child Down's syndrome. Option A
is the same with added analysis for diabetes, cancer and stroke risk.
The cost is exactly the same, since option A is only adding a simple
algorithm to be run on the genome that is obtained in option B. There are
no other costs, no additional risks, no direct physical impacts on anybody,
the number of embryos generated is the same, the number of embryos
discarded is the same, but in option B you only choose to discard aneuploid
embryos, then pick randomly from the remaining ones, while in option A you
discard aneuploid embryos and then pick the healthiest one of the remaining
It is an absolutely clean choice, as clean as you get in real life. The
specific reductions in the risk of diabetes and other conditions are in the
10 - 50 % range. These reductions in disease are the only difference
between the two options.
Is there any situation where taking option B is preferable to option A?
