Unformatted text preview: behavioral comparisons can isolate genetic components for assessment. Dizygotic twins are no more genetically similar than nontwin siblings, but non-twin siblings do not share their prenatal environment, and so comparison can yield opportunities to asses environmental components. Knockout Studies An important technique in molecular analyses of behavioral genetics is the knockout study. Mice are literally designed to express or fail to express certain traits by inserting or subtracting genes from embryonic cells and then reinserting them into a female to gestate. In most knockout studies, a mechanism is designed so that researchers can turn on and off the gene, usually by treatment with an antibiotic. This is accomplished by combining the inserted or deleted gene with another gene susceptible to antibiotics....
