The first study details the generation and structural-functional analysis of mouse/human chimeric hemoglobins and identifies beta-globin chain–specific influences on oxygen binding properties, while the second study examines the genetic modifiers that influence the severity of an alpha-thalassemia–like syndrome resulting from a disrupted embryonic globin gene.
