Only after the landlord got married did she know that her mother-in-law was mentally ill and was afraid of passing the disease on to her children.
Judging from the rambling of the landlord, it is more like a mental patient's thought-just kidding.
In fact, the landlord is worrying too much. Only a small part of mental illness is inherited, and inheritance is also divided into dominant inheritance and recessive inheritance. The landlord's husband is a normal person, which means that he has no genetic disease, and may be a healthy person or a carrier (that is, a normal person with recessive genes will not get sick). As long as the landlord's family has no history of hereditary diseases, then the landlord's children must be healthy children. Even if there are similar mental patients in the landlord's family, the possibility of children getting sick is very low, almost none.
Suggestion:
Let go of the ideological burden and face life happily and positively.
