one method to investigate gene-environment interaction is to study monozygotic twins. identify an example of a twin study ised to examine the gene-environment interraction of a specific disease or condition. briefly sumarize the gene-environment interaction investigated the method and the result. what are other possible methods of studying gene-environment interaction as they relate to improving population health.

Expert Solution

Twin studies. Twins provide a number of ways to study gene-environment interaction. One such method is to study monozygotic twins reared apart (MZA). MZAs provide a unique opportunity to study the influence of different environments on identical genotypes.

For example, the child of an NBA player would probably be exposed to basketball from an early age. Such exposure might allow the child to realize his or her full genetic, athletic potential.

Gene-environment (G×E) interactions are worth studying for several reasons. Consideration of G×E interactions can improve the power for discovering genes that are involved in the etiology of disease primarily through an interaction effect with no marginal effect .

By examining G×E successes, it may be possible to improve the design of G×E studies for the future. In addition, several recent studies examined the use of polygenic risk scores, generated from common genetic variation, to assess the impact of environmental factors on individuals with low versus higher genetic risk

Identify the four types and provide a unique example (one not in the slides/study guide) of each. For the upcoming year, Dorby, Inc. (which has an 8% required return) is expected to produce $10,000 operating income on $100,000 of invested assets by opening its flagship store. Dorby is considering expanding to a second location, which would require an additional $100,000 investment but would produce $9,000 additional operating income. What is the increase/decrease in return on investment (ROI) if the second...

A retrospective study of 159 pairs of twins was performed. The twin pairs each had one male child and one female child. Their birth weights were studied to determine if the male twin was consistently heavier. The difference in weights was calculated by subtracting the female weight (in ounces) from the male weight (in ounces): d=xm-xf After looking at 159 pairs of twins, the study finds the 99% confidence interval for the mean difference of weights (in ounces) is: 2.4...

One example of a 1,3-diaxial interaction is when there are two axial methyl groups on the same side of a cyclohexane ring, called a syn pentane interaction. For cis-1,3-dimethylcyclohexane, the difference in energy between the two chair conformations is 5.3 kcal/mol. What is the energy value (in kcal/mol) of the syn pentane interaction? Show your work, i.e. how you arrived at your answer. You will need to draw both chair conformations of the molecule to properly answer the question. Chairs...
