Quizplus · Accepted Answer

Genetic linkage analysis is a type of study that examines the association between an inherited trait and markers on a specific chromosome or a region of chromosomes. This type of analysis can help identify genetic variations that may be linked to the development of a certain disorder or disease, such as OCD in this case. By comparing the genetic data of family members with and without OCD, the researcher can determine if there is a genetic linkage between OCD and certain inherited characteristics in the family.
