The following table gives the percentage of twin pairs studied in which both twins expressed the same phenotype for a trait (concordance). Percentages listed are for concordance for each trait in monozygotic (MZ) and dizygotic (DZ) twins. Assuming that both twins in each pair were raised together in the same environment, what do you conclude about the relative importance of genetic (H) versus environmental (E) factors for each trait? Traits MZ, % DZ, % H E Blood types 100 66 Eye color 99 28 Measles 95 87 Diabetes 65 18 Mental retardation 97 37
