Blood marriage is marriage between close relatives, such as parents and children, uncles and nephews and cousins, for example, which may pose a risk for future pregnancy due to the increased likelihood of inheriting recessive genes responsible for rare diseases.
The higher the degree of kinship, the greater the likelihood of risk to the future child.In fact, the more the partner has sex with each other, the more likely it is that the recessive genes available to them will be transferred to the baby and that there will be a disease, such as congenital blindness, sickle cell disease, and cystic fibrosis, for example.
- For this reason.
- In the case of marriage between cousins.
- For example.
- It is important to have genetic support to be able to assess all the risks of future pregnancies.
The risks of marriage between cousins are greater because the degree of kinship is close, since there is a greater possibility of combining two recessive genes, one from the father and one from the mother, which have been silenced in the body, with the manifestation of rare diseases The main diseases that can occur as a result of a blood marriage are:
Although there is a higher likelihood of risks associated with sibling marriage, this does not always happen and nearby cousins may have healthy children; However, whenever a bloody couple wants to get pregnant, it is important that the risks are assessed.by the doctor and have the couple monitored throughout the pregnancy.
In the case of a marriage between close relatives, it is recommended that the couple consult a genetic doctor for genetic counseling to identify possible risks that may arise during a possible pregnancy.Understand how genetic counseling is done.
It is during genetic counseling that the doctor analyzes the entire family tree of the pair and genes, checking for the presence of recessive genes and the likelihood of the onset of mental, physical or metabolic diseases in the future child.If there is a risk of foetal change, the partner should be accompanied in order to prepare them to care for the child according to its limitations.
