According to Buddhism, is a child's genetic disease a causal relationship between parents or children?

Well, according to the Buddha, genetic diseases must be inherited by parents. The disease that the youngest son of the last Russian emperor is related to the Queen of England is a family hereditary disease. Cause and effect are in parents. It can be cured in the right way. Figuratively speaking, this disease is like being cursed. It can be passed down from generation to generation, but it can be cured. If there are good families, there will be Qing Yu, and if there are bad families, there will be more disasters. Some genetic diseases, for example, ancestors should not kill animals (such as snakes), and they should not eat the meat of all beings (snakes and turtles). Once they retaliate against one person, they will be fine, but generations will be miserable. Rule, you must first accumulate virtue. Learning the real Buddhism can be cured. And some things, such as diabetes, just eat too much.
