Question
A citizen inquired about the transmission of recessive genetic diseases among relatives and the legal restrictions on marriage within three generations of family.
Answer
Medical professionals explained that while legal laws permit marriage within three generations of family, from a genetic perspective, this practice increases the risk of having a child born with congenital disabilities. Since relatives may share the same recessive genetic diseases, this could lead to a 1/4 chance of having a child with a congenital condition. If there are multiple recessive genetic diseases in the family, the risk increases further. Regarding chromosomal disorders, parents should seek treatment early and use professional methods to help their children recover, thus reducing the impact on their growth and development. Therefore, when a child’s illness occurs, parents should take immediate action to ensure that their child receives effective treatment.
