An interesting research method used by child psychologists to determine which traits and behaviours are inherited is by comparing monozygotic twins and dizygotic twins. This provides a way of isolating genetic influence. The rationale is that since monozygotic (identical) twins are born from the same zygote (an ovum that has been fertilised by a sperm cell), they will have an identical genetic makeup. Dizygotic twins are born from two different zygotes; thus their genetic makeup differs as much as any two siblings genetic makeup would.

For example, in a study to determine if intelligence is genetically determined, the researcher will want to learn if the intellectual capacity of identical twins is more similar, or more closely correlated than that of dizygotic twins. If it is (and this has actually been discovered to be correct), then the evidence indicates that intelligence is largely genetically determined.

Experiments with identical twins have testified…
