Relationship marked by constraints in the quality of the environment the mother faces which necessarily translate into the quality of the fetus"s environment. External constraints internal effects: prenatal constraints can affect postnatal phenotypes. Phenotype what we perceive of the person (outgoing etc. we cant see their hormones) Survival will depend on the nature and intensity of the constrain, in certain cases (iugr) survival is possible but it comes at a cost. : debate on the resulting phenotypes represent. Unavoidable results of prenatal constraints (ie: not enough food therefore, energy for you to grow in impoverished community) *understand these 3 different hypothesis: developmental adaptation results of developmental plasticity. Phenotypic changes are considered to take place in order to survive wither prenatal challenges or expected post-natal constraints. Unavoidable costs don"t have associated benefits to them (other than allowing for immediate survival)
