Question 3: An early criticism of reinforcement theory is that it can only account for the repetition of highly stereotyped behaviors produced in response to specifically trained stimuli (i.e. cannot account for behavior variability, or for the ability of novel stimuli to elicit learned behavior).

Whole genome analyses reveal millions of variants; however, at the present time only a very small number of genetic variations exist for which there are firm associations with disease or a high risk for disease and where morbidity and mortality are increased. However, science is continuously updating the list of clinically relevant variants (Evans & Rothschild, 2012). The requirements for monitoring of whole genome analyses over time are not yet established. Since existence of a known deleterious variant can change...
