Non-invasive paternity testing

Non-invasive fetal paternity testing was an emerging paternity testing method. By collecting the peripheral blood of pregnant women, the next generation of DNA sequence technology was used to sequence and analyze the fetal DNA in the blood, and then compared with the DNA of the presumed father to confirm the paternity. The accuracy of the method was between 95% and 99%. Compared with traditional fetal paternity testing, non-invasive fetal paternity testing did not require invasive samples, and there was no risk or harm to the fetus or pregnant woman. After the sample was collected, the results would usually be out within 7 working days. In urgent cases, the results could be obtained within 48 hours. The advantages of non-invasive paternity testing included no pain, no risk of infection, no miscarriage, and it could be done early in pregnancy. Therefore, non-invasive paternity testing was a safe, accurate, and convenient paternity testing method.

High risk of trisomy 18 syndrome

The high risk of trisomy 18 is related to many factors. From the perspective of the cause, this disease was a kind of abnormality of the fetus. When the parents at home carried the relevant genes, the offspring were prone to the disease, especially the newborns born to older pregnant women were more likely to have trisomy 18 syndrome. In terms of symptoms, children often had a variety of clinical manifestations, such as slow growth and development, craniofacial abnormalities, chest and abdomen abnormalities, delayed development speed, intellectual disability, organ abnormalities, abnormal appearance (small head, rabbit lips, etc.), and obvious abnormalities in bones, genitourinary system, heart, etc. Ectoderm (skin folds, skin ridges, hair, etc.) and entoderm (Meckel's diverticula, lungs, and kidneys) were also abnormal. Moreover, this disease was usually accompanied by severe multiple deformities and had a high mortality rate. 30% died within one month of birth, 50% died within two months, only 5% could survive to one year old, and 1% could survive to ten years old. For pregnant women, if they were assessed to be at high risk of trisomy 18, they should pay attention to relevant prenatal examinations, such as appropriate prenatal screening and diagnosis, which were secondary preventive measures in the prevention of birth defects. At the same time, pre-pregnancy (primary prevention) through health education, eugenics genetic consultation, pathogenic microorganisms examination, careful medication, reasonable nutrition, smoking and alcohol withdrawal and other measures can also help to prevent the occurrence of this disease. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The genetic concept of trisomy

In genetics, there was the concept of a "double trisomy." A double trisomy referred to an organism that had an additional (2n+1+1) pair of diploids. If we mention the trisomatics in the science fiction novel "The Three-Body Problem", from a genetic point of view, it is speculated that due to the three suns on their planet, the special living environment led to the evolution of special physiological characteristics such as the dehydration protection system. Its genetic basis may be the result of a series of mutations, selection, and evolution of genes under the pressure of this special environment. However, the original book did not clearly explain its genetic concept. At present, there was no scientific basis for genetics to indicate the exact concept of genetics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
