• Identical twins are more similar in personality than fraternal twins

What is the heritability of a trait?

• The extent to which variation among individuals can be attributed to their differing genes

What does it mean if a trait has a heritability of 50 percent?

• 50 percent of the trait is genetic and 50 percent is environmental

What is the common genetic profile that makes humans distinct from other species?

• The common sequence within human DNA
