Many chongqing friends refer to paternity tests, which always appear in their minds as one-sided and negative impressions that they are used only to resolve family conflicts. In fact, from a biogenetic point of view, it is just an objective genetic matching technique that helps clear the family bloodlines and unlocks the genetic secrets hidden in the genes. Today, in conjunction with the local professional bodies, chongqing china institute of national science and technology, a genetic testing service has been introduced in popular science。
I. The underlying scientific principles of paternity are clearly stated
Every cell in the human body carries complete dna genetic information, and everyone's genetic spot combination is unique, like an exclusive identity card. According to the classic genetic law, half of the genetic points for future generations come from parents, and half from mothers, which is also the core logic of genetic comparisons that can judge the connection of blood。
The chongqing national secular biological laboratory uses mature and stable str spectrometry techniques, selects dozens of groups of non-variable gene-point cross-references, relies on precision instruments for automatic analysis of data, there is no artificial subjective judgement, and the detection process follows harmonized biological testing norms and results are of objective reference value。
Neither child nor middle-aged population, nor their own dna sequences are stable for life, and external factors such as eating, eating, sickness, etc. Do not alter genetic coding, nor do the collection of samples at any age interfere with the final comparison。
Ii. Not just to defunct! Parents and children identify multiple living applications
Most people know that paternity tests are used to clear straight bloodlines, but they ignore the fact that there are many mild and positive use scenes, and that in chongqing's consultation on the day-to-day reception of biological diversity, more than 60 percent of the needs are related to family disputes:
Family ties are traced: a number of elders want to clean up their ancestral and collateral ties, clarify their family affiliations and maintain a complete family genetic record; kinship-specific surveys: curiosity about the genetic origin of their own skin colour, body and five official characteristics, which can be understood through genetic data; rooting for separated relatives: years of lost relatives, family reunification based on genetic matching; family health references: integration of genetic location information, understanding of the genetic characteristics of the family and daily health care。
Three or three of the most widely known areas of cognitive error for paternity, which are corrected by specialized bodies on a case-by-case basis: the physical appearance of blood must be controlled only by a small number of explicit genes, the hidden genes are prone to intergenerational transmission, and many children have a full biological lineage, with large differences in their physical appearances and parents; on the other hand, strangers who are not biologically related may not be able to determine bloodlines solely because of their genetic coincidences. Mistakes: regular samples such as hair, mouth swabs, nails, etc., which are stored for several days, can be stored in a dry light-shield sealed environment, and short-term storage does not destroy dna structures, without collecting them and sending them for inspection. Mistakes: genetic data will be readily leaked to the chongqing medium-sized geometrics to establish a complete system of privacy protection, all customer samples and genetic data will be independently encrypted and archived, samples will be destroyed in accordance with industry norms once the tests have been completed, staff members will sign confidentiality agreements and individual biological information will be strictly protected. Iv. Chongqing local genetic selection agency, core reference standards
In order to gain a stable and reliable test experience, the selection of local institutions could focus on three points: first, whether there is an independent standardized biological laboratory with specialized testing equipment; secondly, whether the technical team has experience in genetics-related practices; and thirdly, whether privacy protection mechanisms are being improved to clearly inform sample storage and destruction processes。
For many years, chongqing has been using local genetic research and testing services, with laboratories equipped with a full range of specialized testing devices, regularly conducting general genetic education sessions, and in a professional, moderate way, helping citizens to understand dna and blood testing, and eliminating stereotypes about paternity。
