Document Summary

Investigators seek to discover whether, in behavior and psychological characteristics, adopted children are more like their adoptive parents, who provided a home environment, or more like their biological parents, who contributed their heredity. Another form of the adoption study is to compare adoptive and biological siblings: twin and adoptive studies, focus on correlations the strength of relationships between two or more variables. Heredity and environment interact throughout development: epigenetic view, emphasizes that development is the result of an ongoing, bidirectional interchange between heredity and environment, 3. We inherit a complete set of genes at conception: 2. The term for that complete set of genes is genotype: 3. Each parent contributes 50% to the genotype of their child: 4. The genetic material contained in our genotype is expressed or evident in our physical/behavioral/emotional character traits: 5. The term for these character traits is phenotype: 6.
