Question

Robert’s fraternal twin sister Desiree has a diagnosis of schizophrenia. Armend’s identical twin brother, Nigel, also has a diagnosis of schizophrenia. Robert, compared with Armend, probably has a ______ chance of having a diagnosis of schizophrenia. A. lower

Answer 1

Answer:

The correct option is lower.

Explanation:

Schizophrenia can be described as an inherited disease and it is a type of mental illness. As Armend has an identical twin brother with diagnosis of schizophrenia hence, he will have more chances than Robert whose fraternal twin sister has schizophrenia.

As fraternal twins develop from two different eggs hence, the chances in them having the same disease will be lower. Identical twins develop from the same egg, hence they will have more chances of having the same inherited disease.
