The genes are essentially the segments of DNA molecules that contain the code for particular peptides or proteins which then determine who we are (at birth and what we can become - let's not forget about the importance of environment, but the genes give us the starting point). numerically and that the issue can be resolved in a quantitative manner. He thought that parenting is of primary importance to a child's development, and the family as the most important feature of nurture was a common theme throughout twentieth-century psychology (which was dominated by environmentalists theories).

Attachment. Transmission of aggression through the imitation of aggressive models. Several studies have suggested that heritability accounts for about 50% of the variance in aggressive behaviour. Twin Research and Human Genetics, 16(1), 117-125.
