Autosomal DNA statistics describe the connection between the genealogical relationship between two people and the amount of autosomal DNA which they share. Understanding this connection is critical to interpreting the results of an autosomal DNA test. Autosomal DNA is inherited equally from both parents. The amount of autosomal DNA inherited from more distant ancestors is randomly shuffled up in a process called recombination and the percentage of autosomal DNA coming from each ancestor is diluted with each new generation.

When interpreting autosomal DNA statistics, one must be careful to distinguish between the distribution of shared DNA for given relationships and the distribution of relationships for given amounts of shared DNA.

Once you have fulfilled these conditions and are sure that you are entitled to There is no legal restriction on the marriage of first cousins.

If your closest relative is a great grandparent, but there is one generation gap, are you third cousin? Are they removed? The further back the first common ancestor is, the larger the number. First cousins are as close as you can be and still be cousins. It means that the closest ancestor that two people have in common is a grandparent.

Commonly ” cousin ” refers to a “first cousin”, a relative whose most recent common ancestor with the subject is a grandparent. Degrees and removals are used to more precisely describe the relationship between cousins. Degree measures the separation, in generations, from the most recent common ancestor to one of the cousins whichever is closest , while removal measures the difference in generations between the cousins themselves.

To illustrate usage, a “second cousin” is a cousin with a degree of two. When the degree is not specified first cousin is assumed. A cousin that is “once removed” is a cousin with one removal. When the removal is not specified no removal is assumed. Various governmental entities have established systems for legal use that can precisely specify kinship with common ancestors any number of generations in the past, for example, in medicine and law, a first cousin is a type of third-degree relative.

People are related with a type of cousin relationship if they share a common ancestor, and are separated from their most recent common ancestor by two or more generations. The degree is the number of generations subsequent to the common ancestor before a parent of one of the cousins is found. This means the degree is the separation of the cousin from the common ancestor less one. Also, if the cousins are not separated from the common ancestor by the same number of generations, the cousin with the smallest separation is used to determine the degree.

To illustrate these concepts the following table is provided.

The risk of giving birth to babies with genetic defects as a result of marriages between first cousins is no greater than that run by women over 40 who become pregnant, according to two scientists who call for the taboo on first-cousin families to be lifted. Women in their forties are not made to feel guilty about having babies and the same should apply to cousins who want to marry, said Professor Diane Paul of the University of Massachusetts in Boston and Professor Hamish Spencer of the University of Otago in Dunedin, New Zealand.

Although first-cousin marriages are legal in Britain, there have been calls to ban the practice because of reports that it has resulted in a higher-than-average incidence of birth defects in certain immigrant communities where it is common and culturally acceptable. However, Professors Paul and Spencer said that the risk of congenital defects is about 2 per cent higher than average for babies born to first-cousin marriages — with the infant mortality about 4. First-cousin marriages were once quite common in Europe, especially among the elite — Charles Darwin married his first cousin Emma Wedgwood — but that changed in the late 19th-century as people, especially women, became more socially mobile and the risks became more evident.

The stigma attached to first-cousin marriages was supported by early studies into human genetics suggesting that “recessive” versions of a gene which are not expressed unless there are two of them, one from each parent are more likely to be expressed in the children of genetically related parents, as well as more likely to be defective.

There are several different ways religious, secular and civil of solemnising a marriage so that it is legally binding.

In modern western society, marrying your cousin is not well accepted, particularly in the United States. Through a combination of old prejudices and present-day conventional wisdom about inherited birth defects, first cousin marriage is seen by many as a little too close for comfort, as well as a bad idea if you want children. Further, if you include second cousins in the mix, according to the Clinical Genetics Handbook , the increased risks with regards to having children are nearly non-existent in this case compared with non-cousin marriage.

While there have been instances of the banning of marriage between cousins at various points through history, such as the Roman Catholics banning the practice for a time starting with the Council of Agde in AD, for the most part marriage among cousins has been popular as long as people have been getting married.

Nonetheless, the practice soon fell out of fashion in the United States.
