Can consanguineous marriages be intergenerational? First, learn about consanguineous marriage. Consanguineous means having a common ancestor for three generations or less. If they intermarry, it is a more consanguineous mating. It is possible for a consanguineous couple to receive the same gene from their ancestors and pass this gene on to their children. If this gene is inherited in a recessive manner, the children are likely to have mutant pure congeners and develop the disease. Thus consanguineous marriage increases the risk of developing certain chromosome-negative genetic diseases, such as albinism, thalassemia, and schizophrenia. Once recessive inheritance occurs in consanguineous marriages, the risk is high. So it’s not just intergenerational inheritance, but if consanguineous marriages occur, the recessive inheritance of the next generation appears with such inherited genes, so the health risk to the children is very high. Our country currently prohibits consanguineous marriages.
