All embryos are expected to die for sure...
some just become infants, children and adults first.

The problem is that "defective" is not a binary condition.
The definition is VERY subjective.
Is "Down's Syndrome" or "Tay-Sachs" a "defect"?
How about "anencephaly" or any other condition where the embryo could
develop thru pregnancy, but not survive (for long) outside the womb?

If you can't run a control in the experiment, it's bad science.  Don't
do the experiment.
