"Are there genetic predispositions to coffee drinking? Highly unlikely. I referred to this kind of donor selection process as grass roots eugenics—where people select donors based upon fuzzy interpretations of genetics, imagining a prototype perfect donor whose desired traits will be passed down to their child. People choose donors with whom they feel they have a connection. If they plan to tell the child how they were conceived, they also want to be able to say good things about the donor who helped create them."
