Which statement best describes how heredity affects a person’s likelihood of acquiring a mental illness? if a parent or sibling has a mental illness, a person will have the same mental illness. if a family member has a mental illness, a person is more susceptible to having a mental illness. if a parent has a mental illness, a person is less likely to acquire the illness since most mental health disorders skip a generation. if a parent or sibling has a mental illness, a person will be twice as likely to pass the gene to his or her children.

If a family member has a mental illness, a person is more susceptible to having a mental illness.

Explanation:

The genetic traits are responsible for the phenotypic and genotypic characteristic in a living being. These traits are passed on from parents to the offsprings and to many generation of the same family. Thus these traits are said to be heritable. If a family member is affected by the mental illness, then the chances of transfer of genetic trait to the next progeny will be prominent.
