Are children born to cousins deformed?

There is no scientific evidence to support the claim that children born to cousins are more likely to be deformed. In fact, research suggests that the risk of birth defects is only slightly higher for children born to first cousins than for children born to unrelated parents. This risk is still very small, and it is important to note that the majority of children born to cousins are healthy and normal.

The belief that children born to cousins are deformed is likely due to the fact that certain genetic conditions are more common among people who are related. However, these conditions are still relatively rare, and the risk of having a child with a genetic condition is not significantly higher for couples who are related compared to couples who are not related.

It is important to note that there are many factors that can affect a child's health, and genetics is just one of those factors. Other factors, such as the environment, lifestyle, and prenatal care, can also play a role in a child's development.
