Quizplus · Accepted Answer

Twin studies involve comparing identical twins, who share 100% of their genes, with nonidentical or fraternal twins, who share approximately 50% of their genes. Therefore, twin studies are best suited for comparing the effects of genetics versus environment on various traits or characteristics. Longitudinal studies examine changes over time, family studies involve comparing different family members, and first degree studies focus on comparing individuals with a specific familial relationship (e.g. parent-child).
