Question

Which "schizophrenia fact" is correct? select one:

a. when one identical twin is affected with schizophrenia the other most certainly will be affected.
b. copy number variants appear to play the most important role in genetic risk for schizophrenia.
c. when schizophrenia has more genetic influence, its onset begins in very early childhood.
d. because the phenotype of schizophrenia is so obvious, diagnosis and inheritance risk are the most easily determined of all the psychiatric disorders?

Answer 1

The correct fact about schizophrenia is that copy number variants appear to play the most important role in genetic risk for schizophrenia. Both genetics and environmental factors contribute to the development of schizophrenia.

Step-by-step explanation:

The correct fact about schizophrenia is option b: copy number variants appear to play the most important role in genetic risk for schizophrenia. Schizophrenia is a complex psychiatric disorder with a strong genetic component. While genetics does play a role, it is not solely determined by genes. Environmental factors such as stress can also contribute to the development of schizophrenia. Research has shown that individuals with high genetic risk for schizophrenia are more likely to develop the disorder when raised in disturbed home environments.

Answer 2

The schizophrenia fact that is correct is letter d, the copy number variants have appeared to play the most important role in genetic risk for schizophrenia because the copy number variants are likely to be leading cause in order for a schizophrenia to occur or develop.
