Description Data for 577 two-year-old humans who participated in the Boston University Twin Project. Twin pairs were assigned to cluster j, and individuals (monozygotic) or twin pairs (dizygotic) to cluster k. Collection of data for Mental Development Index (MDI) and Elicited Composite Score (EIS) described in doi:10.1007/s10519-007-9160-5; genotyping for 5HTTLPR described in doi:10.1186/1471-244X-10-102. Variable "male" is assigned value of 1 if male, 0 if female; variable "short_allele" is assigned value of 1 if individual has 1 or 2 copies of short allele at 5HTTLPR.
