Adopted and donor-conceived children hold reduced genetic-essentialist beliefs relative to traditionally-conceived children.

For three decades, researchers have assessed children's genetic essentialism through an "Adoption Task," probing their beliefs about whether adopted babies grow up to resemble their birthparents or adoptive parents. The present study investigates these beliefs among children who were themselves adopted or donor-conceived (i.e., who share genetic material with neither or one parent, respectively; "ADC"), comparing them with children who were traditionally-conceived (i.e., who share genetic material with two parents; "TC"). Children (
