Marriage Between Relatives

Marriage between relatives is usually called “Cousin marriages”. Though several ethnicities, cultures, and states allow cousin marriages. There are some states and religions where it is not okay or taboo to marry or date your cousin.

A cousin marriage is the one where both partners are blood related. Such marriages are prominent in ancient times particularly in asian cultures. Even today people are still marrying their cousins, as they think they prove to be good partners. 

However, in some countries it is illegal to marry your cousins, for several reasons. In this article we will explore marriage between relatives as a whole and will highlight every aspect related to it.

Globally, more than ten percent of marriages are cousin marriages, that means people ten percent of the world’s population are either married to their first cousins or the second ones.

The study of cousins marriages is significant in alliance theory, it is a theory used by structuralists where you study the blood relationships in detail. Cousin marriages were really prominent in previous native cultures of North America, Australia, and Polynesia. 

Some cultures prohibit marrying your cousins from first cousin to the sixth one. We observe this practice in some parts of Hindu culture. Whereas, other religions like Islam, Judaism, and Protestantism allows cousin marriages openly.

What is it called when relatives get married?

People having blood relation or relatives when get married, are termed as “Cousin marriages.” Cousins are those blood relatives who share a single common ancestor, let’s say a grandparent or a great grandparent.

The cousin marriages were very common in ancient times and even today some of the religions and cultures promote cousin marriages. 

Scientifically, the marriage between relatives is termed as “Consanguineous relationship.” Such marriages and relationships involve two people who are related to each other by blood, share a common ancestor, and have a coefficient of 0.00516 or may be greater. That means the cousin can be first, second, third, or fourth depending upon the consanguinity coefficient.

Why is marriage between close relatives not allowed?

It is scientifically proven that people who marry their first cousins have higher chances of having children with serious birth defects. That explains if you marry within your family, and particularly your first cousin, there are higher chances of risking your baby’s life, because more than 70% babies born from cousin marriages have birth defects.

Why does this happen? There is a logical and scientific explanation for that. When several members of the same family repeatedly marry each other, some of the genes become dormant or inactive. These genes are called “Recessive genes.” It explains that these genes cannot mutate into something new. Hence, causing birth defects.

It is also true that people who marry repeatedly in the same family are prone to such situations. For example, if your parents, and their parents have marriages within the same family, then there are fair chances that there can be overcrowding of genes within your family.

You can also understand this through this way. For example your parents married in the same family, and now you are looking to marry your first cousin. Now, if you have recessive genes and your partner also has them. Then having babies with that partner means both of the recessive genes will be dominant in the resulting offspring. Hence, more birth defects and abnormalities.
