Reflections on twin relationships: twins reared apart and twins of opposite gender.
The complexities of twin relationships posed by separate rearing and by opposite sex are considered. Unusual cases may highlight unique social-interactional processes and outcomes occurring in these pairs. Research reviews include recent twin studies on second language acquisition, political behavior, and multiple birth rates. Items of more general interest include twin 'cousins' reared apart, indistinguishable monozygotic quadruplets, a genetic testing dilemma, and a performance about separated twins.
