Many couples would love to choose their baby's gender, but this is just the tip of the iceberg when it comes to designer babies. Imagine being able to choose personality traits, hair colour, skin colour and weed out genetic weakness that can lead to ill health?
But designer babies are an ethical minefield. Modern science is both wonderful and disturbing when it comes to this field which will allow parents to pretty much build the child of their dreams from the ground up.
And can undesirable behaviours such as criminal tendencies and lack of concentration really be predicted?
Do you want a child who can sing? Check. How about a daughter who is good at art? Check. A son who excels in sport? Check. A baby that has no genetic predisposition to any type of cancer? Check.
But how accurate can this kind of science be? "Poor impulse control" can now be tested but what if, for example, poor impulse control doesn't just lead to such things as so-called criminal tendencies? What if they also represent other talents such as quick thinking, risk-taking and ultimately the kind of success that can't be predicted?
Any parent who wished for a boy and had a girl, and vice versa, will swear that they are happy they had another boy or another girl. Because each child is a gift. How are we to know exactly what we want when we consider having children or more children?
