A group of scientists from the National University of Colombia documented a case of miscarriages of different parents, during the study of tests applied by a man who cares about the paternity of the nines.
The case was launched in August 2018 when the Genetics Group of Populations and Identification of the National University of Colombia (UNAL) received an application to Establish the paternity of melons with genetic markers, in addition to the parent below the children and need proof.
Following a press release from the National University’s news agency, the implementation of the DNA code of the presumptive father of a family of friends, the Group “evidence that this coincides with the genetic profile of only one of them, is that for another was an exclusion from paternity “.
Scientifically the case is known as heteropaternal superficiency, a rare phenomenon that occurs when an ovulation occurs, released during the menstrual cycle, is fertilized by a spermatozoa of a different sex in separate sexual relations.
Lilián Andrea Casas Vargas, a doctor of Science-Biology at the Universidad Nacional, said that when there are very difficult cases or he wants to be sure of the results of the paternity tests the Laboratory conducts other markets.
In this case, the information aggregates, is a conjugation such as “chromosome Y panel”, claiming that the moles are of the masculine genus, explained Cases.
The procedure
The scientist explained that this procedure is a hermit that is used extensively in marriage. “The chromosome Y is segregated solely by the parent line, and is in the block of a generation to another, never changing”.
“Entones, al not change, it is hoped that these chromosome marketers And are completely identical to the father. In this case, a new genetic profile is observed coinciding with one of the honeycombs, while the other is identified 14 of 17 no coincidences, what corroborates the exclusion “, added the information.
Cases are signaled by established protocols in the laboratory, when a case of paternity is filed and this error as a result of the “exclusion” is repeated throughout the process to correct any technical errors during the analysis.
As well as the newcomer to those involved in the cases, there are other examples and the results of recent cases, as confirmed by the case, which was published in the Biomedical Review of the National Institute of Health.
11,000 years old in Colombia
William Usaquén, director of the group, quoted in the publication, indicates that the country is carrying out a promo of 11,000 proof of paternity this year.
“Although a simple procedure has been followed, it (the test) possesses a very large emotional burden due to the type of social and cultural implications that it has. maternity or sexuality, for example “, says Usaquén.
