Document Summary
Example of gene-environment interactions: temperature-dependent sex determination, women have 2 x chromosomes and men have xy, this is not the case for every species. In birds, female have zw, and male have zz: warm eggs turn male and cold eggs turn female. People who are attractive can do certain things. If sry is on y chromosome so males are more likely to have it: the genes expose you to the experience of being say big and strong or small and weak. Another example of gene-environment interaction: prepared learning: our brain males it easier to learn some associations than others, taste aversion: once you have had too much of a food or drink that it has made you sick. In the future you do not like it anymore: ex. Imprinting: when a baby duck or goose is hatched, it follows the first moving thing that it sees.
