Document Summary
To describe how the mother is the baby"s first environment. To describe intragenomic conflicts and maternal-offspring conflicts. To identify potential times for conflict between mother and offspring. The external environment directly influences the internal environment. Unconstrained: environment is supportive, growth achieve genetic potential. Patterned/channelled: growth shaped by environmental pressures, to achieve better adaptation (developmental adaptation, ex: children who grow up in higher altitudes are better adapted than parents who acclimatated to high attitudes as adults. Constrained: growth is constrained (not reach full potential), impact depends on timing and severity of insults. The relationship between mothers and their unborn offspring is a complex one. This relationship is marked by 2 very important things: constraints in the quality of environment the mother faces which then translates into the quality of the fetus" environment, conflicts of interest between mother and fetus. Plasticity itself is hypothesized to be an evolved trait. Constrained environment (mom) fetus will attempt to adapt to pressures of environment.
