Document Summary
They are completely causal resources for phenotypes. The body cannot break down phenylalanine, a protein that is responsible for mental retardation, seizure, and tremors when concentrated in large quantities in blood. Pku patients missing gene responsible for ordering of amino acids in protein that breaks down phenylalanine. Preventions: avoid diet of foods with the concentration of phenylalanine in milk, eggs, meat and bread. You can avoid the effects if you stick to a strict diet. Monoamine oxidase a is an enzyme that in humans is encoded by the maoa gene. At first pass, low maoa seems to correlate with greater proneness to violence than high, but this depends on early social treatment and experiences of the individual: genetic difference makes no difference with low risk experience in childhood. Two different genetic strains of rats, one naturally pacific, the other provocative and fight-prone, raised in the isolation versus in groups. Rearing conditions either heightened behavioral phenotype or washed it out.
