As of today, GERTRUD 2.0 has launched and now includes close family members in its registry!
By including family members of twins and higher-order multiples, GERTRUD 2.0 expands its research design to incorporate a valuable additional perspective. Information provided by parents, siblings, children, and other relatives enables a more comprehensive understanding of individual development and health. This extended family design helps researchers more precisely distinguish between genetic and environmental influences and better understand how these factors interact.
