Dora has recently started working on a research study that hypothesizes that people who have a defect in a specific gene may have a predisposition to depression. As a second hypothesis in the study, the researcher is studying the impact of a significant lack of social support in triggering the onset of depression in such people. If Dora’s research successfully validates both hypotheses, which of the following conclusion may be drawn?

Question

anonymous · Answer

A defect in the gene Dora is studying is directly linked to depression.

		
A lack of social support always leads to clinically significant levels of depression.

		
The defective gene and lack of social support produce a heightened risk of depression.

		
The defective is recessive and depression is a result of polygenic inheritance.
