Пояснення:

Резус-фактор (Rh-фактор) — это белок, который обычно присутствует на поверхности красных кровяных клеток у большинства людей (их называют Rh-положительными). Однако у некоторых людей этот белок отсутствует (они являются Rh-отрицательными). Резус-фактор имеет значение в медицине, особенно при трансфузиях крови и беременности. Несоответствие резус-факторов между матерью и плодом может вызвать проблемы для беременности и требовать медицинского вмешательства.
