Canalization : sometimes attributes are predetermined and you need envrionmental factors to push them outta that. Gottesman, each person"s unique genetic structure, it determined the response to the environment that people have. The genotype will actually set the limits on the range of possible phenotype that an individual will portray. Ex: child a b and c child a has great genetic perspective of intelligence, b medium and c doesn"t have. It sets the range under which the child can express intelligence in regards to the environment. Look at the childs intelligence in genetics in respect to environments. You see in child a in the restricted environment they don"t do as well same with b and c. First idea: the range of child a is the limits, it is really big, so having good genetic potential, gives the child a large range to fall into. Compared to the child c has limited genetic potential has more of a restricted range.
