So where genetic selection aims to bring out a trait that clearly benefits an individual and society, we should allow parents the choice.
To do otherwise is to consign those who come after us to the ball and chain of our squeamishness and irrationality.
Indeed, when it comes to screening out personality flaws, such as potential alcoholism, psychopathy and disposition to violence, you could argue that people have a moral obligation to select ethically better children.
They are, after all, less likely to harm themselves and others.
If we have the power to intervene in the nature of our offspring – rather than consigning them to the natural lottery – then we should.
