内容摘要

Twin research informs our thinking about possible human reproductive cloning (HRC). Other human models for assessing the benefits and difficulties of HRC are look-alike parent-child and sibling pairs. An in-depth interview with an extraordinary mother-daughter pair is provided. This section is followed by reviews of research on infantile pyknocytosis in a dizygotic (DZ) twin, monozygotic (MZ) twin discordance for hemimicrencephaly, unusual dental development in a twin, and 'gaze fingerprint signatures'. The final section presents human interest stories of identical twin executives at odds, the loss of identical twin Jim Whittaker, identical twin artists, and twin wisdom captured in stone.
