Can I pick my baby’s eye color?
While a baby’s eye color can sometimes be predicted by looking at his or her parents’ eyes or those of other relatives, genetic variations can lead to unexpected results. Currently, genetic engineering allows us to select our baby’s gender and eye color as well as modify the risk of certain illnesses.
