Study Notes
Twin Studies
- The primary aim of twin studies is to separate the effects of genetic and environmental factors on human behavior, development, and health.
Value of Twins in Research
- Twins are considered a valuable source for observation in research because they share the same womb, are raised in the same family, and have similar environmental factors.
Monozygotic (MZ) Twins
- 'Identical' or monozygotic (MZ) twins share 100% of their genes.
Application of Twin Research
- The field of behavior genetics considers twin research a key tool.
Alternative Methodology
- Apart from twin studies, another methodology used in behavior genetics is adoption studies.
