Why is it necessary to study human heredity?

Human heredity is studied for several reasons. The main reason is to predict the likelihood of a genetic disorder in a child. Such an opportunity has appeared recently. Thanks to special tests, it is possible to determine whether a genetic disease can be transmitted from a father or mother to a child and what is the likelihood of this. Thus, you can apply methods that can minimize the chances of transmission of the disease or prevent it completely. These tests are very accurate, but they still improve. That is why it is necessary to study heredity.
