London, Feb 10 (IANS) You can thank your genes more than your upbringing for being a do-gooder in real life.

Psychologists from Edinburgh University in Britain surveyed 958 pairs of twins, including 361 pairs of identical ones, to work out the effects of genes and upbringing, the journal Biology Letters reports.

They found that genes influenced a woman’s ‘civic and work obligations’ (behind being a do-gooder) more than they did a man’s, according to an Edinburgh University statement.

Family environment seems to govern men’s behaviour more than genes, the study said.
