Patient's question:
How can I tell if my girlfriend and I are close relatives getting married? My girlfriend and I are from the same village, and our families are not far apart! If you trace our family line, my great-great-grandfather and her great-great-grandfather's father (might be) the same person. My girlfriend's mother has always believed that we are close relatives getting married and has been strongly against it, saying she's afraid our children might not be healthy. So, I wonder if there's any way to test whether we can have children and if we are healthy? Just to put my mother-in-law at ease!Doctor's answer:
According to the situation you described, your situation can be married, and it will never interfere with the next generation. According to the Marriage Law of our country, direct blood relatives and collateral blood relatives within three generations cannot marry. Your situation has collateral blood relatives within six generations, so you can get married. Of course, the farther the blood relationship, the better. You can check the chromosomes carefully, and the main thing is to see if there are any hereditary diseases in the family. Wish you a happy life!
