Document Summary

Hair colour in inuit (hair colour is all black)- h2= 0, because there is not variability. Heritability of intelligence: notion seems reasonable: oskar stohr and jack yufe- separated at birth. Both of them were so similar when they met. They are so similar, there must be a genetic contribution: family relationship studies- twin studies use this. Important assumption: no environmental differences for identicals versus fraternals, looks at identical and fraternal twins, gives them dna tests to make sure they are identical or fraternal. Identical twins who thought they were identical= 0. 66. Identical twins who thought they were fraternal= 0. 77. Identical twins who thought they were identical= 0. 81. Identical twins who thought they were fraternal= 0. 85. Fraternal twins who thought they were fraternal= 0. 81. Fraternal twins who thought they were identical= 0. 78. Fraternal twins who thought they were fraternal= 0. 93. Fraternal twins who thought they were identical= 0. 77.
