Question

Quizplus · Accepted Answer

Research has shown that a particular allele variant of the serotonin transporter gene SLC6A4 can make children especially reactive to their rearing environment. This means that they may be more susceptible to positive or negative aspects of their upbringing, such as being more likely to develop behavioral problems if they experience abuse or neglect, or more likely to thrive if they receive positive and supportive care. The other options-- low in fearfulness, particularly high in moral reasoning, and aggressive-- are not strongly linked to this particular allele variant.
