First Cousin Legal Australia
Andrey Korotayev claimed that Islamization is a strong and significant predictor of the marriage of a cousin (daughter of the father`s brother – FBD), bint `amm marriage. He showed that while there is a clear functional link between Islam and FBD marriage, the recipe for marrying an FBD does not seem sufficient to convince people to marry in this way, even if marriage brings economic benefits. According to Korotaev, a systematic acceptance of marriage between cousins took place when Islamization took place alongside Arabization.  A marriage is void (i.e., legally, the marriage never took place) if one or both parties are already legally married to another person at the time of the marriage (section 23 of the Marriage Act). This is known as “bigamy”, a crime punishable by up to seven years in prison (section 360 of the Penal Code Act 1899 (Qld)). If a significant blood marriage has been concluded, one or both parties may apply to the court for a judgment of nullity annulling the marriage. Texas banned marriage to first cousins the same year Amrhein and Andrews married, apparently in response to the presence of the polygamous fundamentalist Church of Jesus Christ of Latter-day Saints (FLDS). Texas Rep. Harvey Hilderbran, whose district includes FLDS headquarters, drafted an amendment to a child protection law to prevent flds from moving to Texas and “prevent Texas from succumbing to practices of taking child brides, incest, social abuse, and domestic violence.”  Although Hilderbran explained that he had not drafted a bill banning only marriage to first cousins, he also stated in an interview, “Cousins do not marry, just as siblings do not marry. And when that happens, you have a bad result.
This is simply not the accepted normality.  Some sources of information then mentioned only the provisions on polygamy and child abuse, ignoring the part of the law dealing with marriage between cousins, as did some more recent sources.     The new law made sex with a first-degree adult cousin a more serious crime than with adult immediate family members. However, this law was amended in 2009; While sexual relations with close adult family members (including first-degree cousins) remain a crime, the harshest punishment is now associated with sexual relations with a person`s direct ancestor or descendants.  Regardless of whether you agree with the morality and science behind the marriage of a first cousin, here we are only interested in the legal aspects of the subject. As long as you are not forced to marry a relative, if you really want to marry your sweet cousin, this is your legal and personal prerogative. In April 2002, the Journal of Genetic Counseling published a report that estimated the average risk of birth defects in a child born to first-degree cousins at 1.1-2.0 percentage points above an average baseline risk for non-cousin couples of 3%, about the same as that of a woman over the age of 40.  In terms of mortality, a 1994 study found an average rate of excessive pre-reproductive mortality of 4.4%, while another study published in 2009 suggests that the rate could be closer to 3.5%.  In other words, a marriage to a single first cousin carries an equally increased risk of birth defects and mortality as a woman when she gives birth at age 41 and not at age 30.  “Learning that someone is capable of marrying their uncle or cousin was very shocking, given that same-sex marriage has only recently been legalized,” Helena said.
Repeated blood-related marriages within a group are more problematic. After repeated generations of cousin marriages, the actual genetic relationship between two people is closer than the most immediate relationship suggests. In Pakistan, where there has been a marriage of cousins for generations and where the current rate can exceed 50%, one study estimated infant mortality at 12.7% for first-degree married cousins, 7.9% for first-degree cousins, 9.2% for first-degree cousins/second-degree cousins, 6.9% for second-degree cousins, and 5.1% for unrelated second-degree descendants. Among first-degree dual offspring, 41.2% of pre-breeding deaths were associated with the expression of harmful recessive genes, with equivalent values of 26.0, 14.9, and 8.1% for first degree, first-degree cousins/second-degree cousins, and second-degree cousins, respectively.  The Hindu Marriage Act prohibits marriage for five generations on the paternal side and three on the maternal side, but allows marriage between cousins if custom permits.   You can also marry your cousin. if you`re into something like that. Marriages between cousins have genetic aspects that have an increased chance of sharing genes for recessive traits. The percentage of inbreeding between two individuals decreases by four times because the youngest common ancestor dates back a generation. First cousins have four times more blood ties than second cousins, while first cousins have half of those of first cousins.
Double first cousins have twice as many as first cousins and are just as related as half-siblings. Many of Muhammad`s immediate successors also took a cousin as one of their wives. Omar married his cousin Atikah bint Zayd ibn Amr ibn Nifayl, while Ali married Fatima, the daughter of his paternal cousin Muhammad and thus his first cousin.  Kreuzcousinen marriage also establishes a separation between prescribed and prohibited parents, who are strictly interchangeable from the point of view of biological proximity. Lévi-Strauss believed that this proved that the origin of the prohibition of incest was purely social and not biological. Marriage between cousins allowed the anthropologist to control the biological degree by studying a situation in which the degree of forbidden and prescribed spouses was equal. To understand why two parents of the same biological degree would be treated so differently, Lévi-Strauss writes, it would be possible to understand not only the principle of marriage between cross-cousins, but the prohibition of incest itself. For Lévi-Strauss, marriage between cousins is neither socially arbitrary nor a secondary consequence of other institutions such as dual organization or the practice of exogamy. Instead, the raison d`être of the marriage between cross-cousins could be found in the institution itself.
In fact, a quarter of all marriages between Turks in Germany are marriages with a relative of the family, according to a survey by the Center for Turkish Studies in Essen.  Roman civil law prohibited marriages in the four degrees of consanguinity.  This was calculated by counting from one potential partner to the common ancestor and then to the other potential partner.  Early Medieval Europe continued the late Roman ban on marriage between cousins.
