accidental trisomy loss
The accidental loss of trisomy in the embryo referred to the occurrence of trisomy (one more of a certain number of embryos) and the loss of a single embryo. This situation happened by chance. In terms of trisomy, trisomy 16 was a serious aberration, which could easily cause embryo arrest or stillbirth; trisomy 22 was caused by the non-separation of the autosome in the fertilized egg during Meiosis, which was one of the common abnormalities of the early stage of pregnancy. Postnatal survival cases were rare. If there were many functional genes in the fetus, the fetus would usually be difficult to develop. For example, the 21st, 13th, and 18th embryos were relatively short and did not contain so many genes. The fetus might survive in the trisomy state. For example, the pathogenic loss of the 15q11.2 region of the fetus's fetus would make it difficult for the embryo to mature naturally. Chromatic micro-loss and micro-repetition syndrome was a group of mutations. It was caused by the loss or repetition of a small gene on a gene, resulting in a change in the number of normal genes, which led to a variety of clinical manifestations, such as multiple abnormalities after birth, low intelligence, stunted growth, or fetal arrest. It mainly depended on whether the mutation was in a critical area. Embryonic triploids may be accidental or hereditary. It may be related to drugs, diet, and environmental factors. These factors may cause inheritance. If both husband and wife have normal chromosomy, there may be genetic mutations during embryonic development, or abnormal unseparated chromosomy during Meiosis. This kind of accidental situation generally does not affect the next pregnancy, but if the next pregnancy, relevant examinations are still needed. For example, pregnant women should actively receive examinations during pregnancy. If the abnormality of the chromosomy is confirmed, the pregnancy may need to be terminated. Couples with a history of genetic diseases, elderly pregnant women, high-risk pregnant women with a history of adverse fertility, and unexplained fetal arrest and miscarriage should undergo early screening.

Was the trisomy good?
As a fan of online novels, I can't judge whether a novel is good or not because everyone's tastes and preferences are different. However, according to my knowledge of online novels," The Three-Body Problem " is a very successful science fiction novel that has won a wide readership and many awards. This book talked about the confrontation between human civilization and extraterrestrial civilization, involving many scientific concepts and philosophical thinking. It also explored the progress of human civilization and the future direction of many other topics. If you're interested in science fiction or have a deep understanding of scientific and philosophical thinking, then The Three-Body Problem may bring you great reading pleasure.
Was the trisomy good?

The story of this novel is thrilling and profound, which is of great help to the readers 'shock and imagination.
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>
Trisomy of the Tang Dynasty 1:196
The ratio of 1:196 belonged to the high risk range of trisomy 21 syndrome (1:380 was considered high risk) or trisomy 18 syndrome (1:350 was considered high risk, and there might be some deviation between different hospitals). The high risk of screening for Down syndrome did not mean that the fetus would definitely have abnormalities, but it meant that the probability of trisomy syndrome was greatly increased. It was suggested that non-invasive DNA or an amniocentric puncture should be further performed. The accuracy of these two tests was about 99%, which could effectively rule out the probability of the birth of a fetus with Down syndrome. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Trisomy of the Tang Dynasty 1:59
The test results for trisomy 21 syndrome were 1:59, which was in the high-risk range, indicating that the fetus was more likely to have trisomy 21 syndrome. Since the screening test was only a screening test and not a definite diagnosis, when the screening test found a high risk, a further examination of the fetus's fetus was needed to determine whether there was a problem with the fetus's fetus. If the DNA test after the puncture was normal, the pregnancy could be continued; if the diagnosis was confirmed to be Down's syndrome, termination of the pregnancy should generally be considered. There were no special precautions for pregnant women, but they should try to arrange for an annulment as soon as possible after the examination to avoid missing the examination time and to avoid mental tension. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Trisomy 18 Critical Danger
The critical risk of Trisomy 18 usually meant that the risk value was between 1:270 and 1:1000. If this happened, there were two choices according to national standards: one was to do a non-invasive DNA test, which was the priority; the other was to do an amniocentric puncture, but the abortion rate of puncture had to be considered. If the risk of Tang screening was lower than the abortion rate of puncture, it was more appropriate to do a non-invasive one. Non-invasive DNA testing was also a prenatal screening method. It was used to extract fetal DNA fragments from the venous blood of pregnant women to screen for trisomy 21, trisomy 18, trisomy 13, and some other hereditary problems. Amnioception was the final method of diagnosis, but there was a risk of miscarriage. It should be noted that the screening test was only a screening method, not a definite diagnosis. Even if the screening test indicated a low risk, it could not completely rule out the abnormality of the Karyotype. The pregnancy test should be carried out on schedule. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Trisomy of the Tang Dynasty 1:870
The ratio of 1:870 was between 1:1000 and 1:270, which was a critical risk range for trisomy 21 syndrome. This meant that the risk of the fetus suffering from trisomy 21 syndrome was in a relatively intermediate state. It was not a definite diagnosis of the fetus having a hormonal abnormality, but the probability of the fetus suffering from trisomy 21 syndrome was increased compared to the low risk value. In this case, it was usually recommended to further perform a non-invasive DNA test or an annulment test to determine if the fetus had any hereditary diseases. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Non-invasive Trisomy 2.3
Only the term "non-invasive trisomy 2.3" was very vague. If the "non-invasive trisomy" here referred to the content of trisomy 21, trisomy 18, and trisomy 13 in the non-invasive DNA test, then the non-invasive DNA test report would usually give a numerical assessment of the risk of these three types of aberrations. However, it was not clear what kind of trisomy the value of 2.3 was, or if it was some other relevant value (such as the risk ratio). Under normal circumstances, these values were used to assess the risk of the fetus suffering from the corresponding hormonal disease. If the values were abnormal, further prenatal diagnosis was needed to confirm whether the fetus was really sick. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Are there any Trisomy 13 success stories?
Yes, there are some Trisomy 13 success stories. Some children with Trisomy 13 have defied the odds and lived longer than expected. Through early and aggressive medical intervention, like surgical corrections of some congenital anomalies and proper management of associated health issues, they have been able to have a better quality of life for a certain period. However, it's important to note that Trisomy 13 is a very serious chromosomal disorder and the overall prognosis is still quite challenging.
