What is heritability coefficient and how have researchers used it to compare genetic and environmental influence on behavior?
What will be an ideal response?
Answer:
• Heritability coefficient—statistical estimate that provides information on how much genetic factors influence variance in a particular trait.
• Twin studies represent a natural experiment that can be capitalized upon to answer questions.
• Scientists use information from these types of twins to produce estimates about whether and how much genetic or environmental factors influence the development of trait.
• Twin studies focus on concordance rates of MZ (identical twins) and DZ (fraternal twins) twins.
• Environment is same for both types of twins, therefore, the genetic affect or environmental effect can attribute for developing trait.
• MZ start out as one zygote and share all of their DNA and can be considered genetic clones of one another.
• DZ begin life as two separate children and only share 50% of their DNA just like any other set of normal siblings.
• Larger heritability coefficient, the more genetic influence
• Smaller heritability coefficient indicates the environment is identified as playing larger role in trait variance.
