What is genetic attraction? The closer the blood relationship, the heavier the genetic attraction

Genetic attraction occurs in adults who are closely related by blood. Generally speaking, they have not lived together for a long time, or have never seen each other before. The first time they meet after sexual maturity, the same genetic genes will make one person and both parties have instinctive sexual attraction. This sexual attraction is stronger than that of people who are not related by blood. Genetic attraction occurs not only between brothers and sisters, but also between parents and children, Grandparents and grandchildren also experience this phenomenon.

The phrase 'hereditary attraction' seems to have been created by a woman named Barbie Gonia. Because when she reunited with her 26 year old son, who had been abandoned since her infancy, she was startled by the lust in her mind. Her desire for her son never became a reality because his love for her was not appreciated, and when she got married, Gonya's feelings for her son began to fade.

But her book says that this romantic idea of love and sex may be due to the lack of close relationship between mother and newborn in the early stage. Which child of a brother or sisters cannot live together in the early stage, and it must be made up for in the future. Many people who encounter this situation need to experience the intimate relationships that should have emerged in the early stages of adulthood. This relationship may or may not evolve into a sexual relationship.

Genetic similarity makes it easier for each other to develop charm

Usually, people tend to have a better impression of people who are similar to themselves, and the other person is more attractive and reliable. When people are looking for a spouse, they also like to look for people with similar interests and personalities. People with blood relationships have great similarities in personality, which is prone to this phenomenon. When parents and their children have genetic attraction, parents often treat their children as their spouses to love them, because their children are likely to inherit their spouse, regardless of their appearance or personality.

The theory of anthropologists is that people who are close to blood have the same genetic composition and usually have similar appearances, personalities, and interests. They are easily attracted to each other and resonate strongly with the same sex, which is called hereditary charm, but opposite sex develops into hereditary charm.

However, such feelings do not occur between brothers and sisters who grew up together as children. Children have never left their parents, and generally do not have feelings of genetic attraction to children. This is the so-called Westmark effect. This theory suggests that people who grow up in the same family will find themselves without sexual attraction to each other, and even if there is strong social pressure to pair them, they will develop psychological exclusion, and humans have an instinctive aversion to incest.
