Document Summary

Correlation: esti(cid:373)ate of si(cid:373)ila(cid:396)ity i(cid:374) t(cid:449)i(cid:374)s" t(cid:396)aits, ranges from 0. 00 to +1. 00. Concordance: what percent of the time do twins both show a trait, ranges from 0 to 100, discontinuous (all-or-none) traits. Include both adoptive and biological kids: compare (r) for biological parents + kids and (r) for adoptive parents + kids, r adopt = r biol environmental evidence, r adopt < r biol genetic evidence. Compare identical twins raised together (same environment) to those raised separately (different environments) rmz > rmz(d) - environmental evidence rmz(s) = rmz(d) genetic evidence (cid:862)ho(cid:449) much(cid:863) (cid:448)s.
