What Is Genetic Sexual Attraction?

Even in the animal world, many populations avoid inbreeding and prevent population degradation. This is a protection mechanism for species formation over millions of years, known as the genetic detection mechanism, and there is a phenomenon that is just the opposite, which is called "hereditary attraction "The closer the blood is, the more obvious the effect will be. The brothers, sisters or siblings who have not grown up together will have a natural sexual attraction. This is caused by the same genetic genes between the two sides, and even between parents and children People with grandparents and grandchildren may also have a "hereditary attraction" phenomenon.

Even in the animal world, many populations avoid inbreeding and prevent population degradation.

The phrase "hereditary attraction" seems to have been coined by a woman, Barbara Gunniya. When she reunited with her 26-year-old son who had been abandoned in her infancy, she was taken aback by the lust in her head. Her desire for her son has never become a reality. After all, her son's love for her is not appreciated, and after marriage, this feeling of Gonia also began to fade.

A book she wrote explains the feeling as follows: "This romantic love and sexual thought may be caused by the lack of early intimacy between the mother and the newborn baby, or it may be one of the siblings In the early days, you cannot live together because of foster care to make up for the consequences of this lack of affection. Many people who encounter this situation need to experience the kind of intimacy that should have appeared in early life. Once this relationship occurs, It may or may not evolve into a sexual relationship. "

Hereditary attraction usually occurs when

Genetic similarity makes each other more attractive

Generally speaking, people are more fond of people who look similar to them, and find them more attractive and trustworthy. When people are looking for a spouse, they also like to find people with similar interests and similar personalities, but people with blood relationship have a great similarity in personality, which is easy to happen. When parents and children are genetically attracted, parents often treat their children as their spouse to love. It is very likely that the child's appearance and personality will inherit the characteristics of the spouse.

Anthropologists' theory is that people with similar blood origins have the same genetic composition, and usually have similar appearances, personalities, and interests, which will make them more attractive to each other. If there is a strong sense of identity between the same sex, This is called "hereditary attraction" and can develop into "hereditary attraction" if it is between the opposite sex.

However, siblings who have grown up together do not have such feelings. Children have never left their parents, and they usually do not have "hereditary attraction" to their children. This is the so-called "West Mark effect. " The theory believes that people who grow up in the same family will find that they are not sexually attractive to each other. Even if there is strong social pressure to force them to pair, they will have psychological rejection, and humans have an instinctive aversion to incest.

Li Yao, a professor at the Institute of Genetics, School of Life Sciences, Fudan University, believes that this view is more one-sided. She said that love between men and women is a very complicated matter. Some people, even with similar appearances, personalities, and interests, will not develop into lover relationships. Complementary lovers are often opposite in all aspects. Li Yao believes that just from the perspective of genetics, it cannot comprehensively and objectively explain the phenomenon of falling in love with brothers and sisters or sisters who have not grown up together, let alone why this kind of thing rarely happens to brothers and sisters who grew up together. between.

Results of Psychological Research

Psychological studies have shown that "hereditary attraction" should exist. A 1995 British Journal of Medical Psychology report stated: "People's relationships are related to their perceptions of each other. It's like family relationships, and you will find each other receiving ethics. The relationship is interactive and indescribable. Researchers are surprised to find that more than 50% of children fostered elsewhere have a strong urge to have sex with their family when reunited with their family. "
