What is the relationship between the intelligence of three generations of IVF and genes?
The third generation of test tube baby refers to the use of the eggs or sperm of the third generation of relatives to make them pregnant, and finally successfully foster the baby to their relatives' children. Compared with traditional IVF, the third generation IVF has more advantages, such as reducing the harm of IVF to women and improving the success rate. However, many people have doubts about the intelligence of the third generation IVF, and believe that genes will affect its intelligence level. So, what is the relationship between the intelligence of three generations of IVF and genes?
1. Genetics and IQ
IQ is a measure of a person's intelligence level, which is largely affected by genetic factors. Many studies have shown that there is a certain correlation between IQ and genetic genes. The parents' IQ level is high, and the children's IQ level is often high. This means that the IQ of three generation IVF babies may be affected by their relatives' genes.
For example, the study of the University of California, Los Angeles, found that IQ is affected by genetic factors about 60% to 80%. This shows that the heritability of IQ is similar whether through natural pregnancy or IVF technology. Therefore, it can be said that the intelligence of three generations of IVF is closely related to genes.
2. Artificial selection and high-quality genes
An important factor related to third-generation IVF technology is manual selection. By screening and selecting high-quality genes, children's IQ level can be increased to a certain extent. For example, in some countries, when choosing or donating sperm, both husband and wife will pay attention to their IQ level, educational background, family history of genetic diseases and other factors. This method of selecting high-quality genes can improve the potential intelligence level of three generations of IVF.
However, it is worth noting that, even after artificial selection, the role of genes in intellectual development is only a potential factor. Children's wisdom is also affected by the acquired environment. Education, family, society and other factors will affect children's intellectual development.
3. Education and intellectual development
Education is essential for intellectual development. As a family member, the third-generation IVF will receive educational opportunities similar to those of other family members, which will affect its intellectual development to a certain extent.
In a high-quality educational environment, children will be exposed to more knowledge and learning opportunities to develop their thinking ability and creativity. This will help to improve the intelligence level of three generations of IVF.
However, even in the same educational environment, each child's intellectual development is also different. This is because intelligence is a complex feature, affected by many factors, including genetic factors and environmental factors.
4. Summary
To sum up, the intelligence of three generations of IVF is closely related to genes, and genetic genes play a decisive role in the development of IQ. By artificially selecting high-quality genes, children's intellectual potential can be improved. However, education is also a key factor in intellectual development. High quality educational environment can help the three generations of IVF to develop their potential intelligence. In general, the intelligence of the third generation IVF is the result of the combined influence of genes and environment.
