The researcher is comparing people with and without a particular disorder and is interested in inherited tendencies that occur with much greater frequency in afflicted people. This describes an association study, which is a type of genetic study that examines whether there is a statistical association between genetic variations and a particular trait or disease. Genetic linkage analysis looks at the co-occurrence of genetic markers and the disease phenotype within families. Family studies involve examining the occurrence of disease within families to estimate the risk of developing the disorder. DNA analysis can refer to a variety of techniques used to study DNA, but it is not a specific type of genetic study.
