Document Summary

Genotype: genetic constitution of an individual. Phenotype (of an individual organism: describes one of its measurable traits or characteristic, example. Blue eyes or aggressive behavior: controlled by. Genes but also significantly affected by environmental factors. Person"s language: relationship (interaction between genotype and phenotype) Per-olof astrand: close to 100% of the biologic existence of humans was adapted to an outdoor existence of hunting and foraging for foods. Optimal health: exercise is not optional, sedentary individuals have a much greater chance of a poor phenotype (chronic disease) than active individals, sedentary. Accustomed to sit or rest a great deal. Take little exercise: sedentary lifestyles and diets based largely on processed foods do not match human genetic make-up and have wrecked havoc on the health of the north american population. Epigenetics: study of heritable changes in phenotype (gene expression) caused by mechanisms other than changes in the underlying dna sequence.
