The probability of identical twins
Identical twins, as the name suggests, refer to two fetuses that develop at the same time in the same mother. They have the same genetic sequence and can be distinguished by a permanent ID. Identical twins are a rare condition in childbirth, with an incidence rate of about three to four in 1,000. Next, we will decipher the mysterious code of fetal development from four aspects, namely genes, environment, modern medicine and mysterious status.
Genes influence the occurrence of identical twins
Identical twins are formed from the splitting of a fertilized egg, so they have exactly the same genetic sequence. Non-identical twins are 50% genetically similar to ordinary siblings. In identical twins, the parents\’ genes become the only source of twins. Humanity\’s understanding of genes is still largely unknown. Recent studies have shown that genes encoding structural proteins have an important impact on the development of twins. Data show that patients with changes in genes encoding structural proteins are the main reason for the increased rate of identical twins.
The environment also affects the development of twins
Identical fetuses are cleavages of a fertilized egg, and their first division occurs in the human body. Therefore, the health environment of twins will play a key role in their growth. They may share the same perceptions and memories, weight, gender orientation, blood type, and IQ.
Some external conditions during childbirth also have an important impact on the development of identical twins. Especially during the gradual growth of the mother and the postpartum period, because the blood of the two placental suckers of the twins is not evenly distributed, the mother may suffer a certain degree of damage.
Modern medicine has increased the incidence of twins
Although the occurrence of identical twins is related to genes and environment, modern medicine has become an important reason for the increased incidence of identical twins. At present, the development of assisted reproductive technology, especially in vitro fertilization technology, has greatly increased the probability of multiple births. Jennifer Aniston is an example of what happened to twins who used IVF specifically for this purpose. Especially in the past few years, IVF technology has continued to develop, and with the legal support of some countries, it has been widely used to achieve pregnancy.
The legend behind the mysterious twins
Mysterious conditions such as identical twins have always aroused curiosity and suspicion. Many books, movies and cultural works with twins as the theme have been produced. Many classic movies such as \”Pride and Prejudice\” and \”Happy Burger\” also show the unique legendary charm of twins from the perspective of the twin actors.
Generally speaking, the probability of identical twins occurring during childbirth is very small, but they have a mysterious and legendary existence and deserve more attention. Their probabilities are influenced by genes and environment, and modern medicine offers rich and novel options for reproductive women. People can learn more about genetics and reproductive health through this phenomenon.
