Dear LFTP: the genetics letter — "was my dad really my dad?"

  • My traits don't match my parents — was my dad really my dad, and should I ask?

A biology student writes that his recessive traits don't match his parents and fears an affair he doesn't know about. The hosts say ask — awkward, but the mother likely knows and genetic medical history matters — then role-play the conversation ('Ma, I have blue eyes. Y'all don't have blue eyes'). They land on: your identity is unchanged by what you learn ('it was already true'), God may be setting you up for forgiveness, and you could be 'the Joseph in Egypt' bringing a new family out of famine. Secular's advice: talk to your parents to get the full family trait history from other generations.
