Genetic studies of families with members who have been diagnosed with schizophrenia have
yielded results that support all but which of the following results?
a. The probability of developing schizophrenia is higher for an individual whose siblings
have been diagnosed with the disorder.
b. The probability of developing schizophrenia increases with the number of relatives who
are diagnosed with the disorder.
c. Concordance rates are higher in monozygotic than dizygotic twins.
d. Specific genetic aberrations or defects have been found which are believed to be the
cause of the high concordance rates between family members with schizophrenia.
e. The closer the relation to the individual who has schizophrenia (e.g., first degree as
compared to second degree relatives), the greater the probability of developing the
disorder.

A model genetic system, the fern Ceratopteris richardii
A genetic bottleneck reduces a population temporarily to very low levels, removing much of its genet
The lifetime risk for schizophrenia varies with the degree of relationship to an affected individual
