So the bf carries the schizophrenia gene, what is the chance that our child could have it?

12% chance: One possible cause of schizophrenia may be heredity, or genetics. Some people may inherit a tendency to schizo.. In fact, the disorder tends to run in families- among blood relatives. People who have family members w/schizophrenia may be more likely to get the disease themselves. If both biologic parents have schizophrenia, there is nearly a 40% chance. If 1 bio parent has Schiz. 12% chance.
