Which hair color is the most "amorous"?

A new discovery confirms that the gene that determines hair color in humans can reveal a lot about the owner's loyalty and "promiscuity".

Scientists say the genes that determine hair color are closely linked to when and how someone has sex. People with naturally red hair - both men and women - tend to delay their first sexual encounter later than people with other hair colors such as black, brown, blonde...

Another interesting finding is that women with freckles on their faces also tend to “keep” them more, although this is not true for men with freckles. That’s because both hair color and freckles in women are determined by a gene called MC1R.

Genes that determine hair color also affect your level of "playboy"

Genes also play a surprisingly important role in determining the age at which a person will experience "sex" for the first time, the number of sexual partners they have, how many children they will have later in life, and even predicting whether a person may become infertile, scientists claim.

In fact, the genes that determine hair color are just one of 38 groups of genes that can influence sexual behavior in humans. A "risk-taking" gene called CADM2 makes the subject more likely to have sex earlier than others, as well as have more sexual partners. In other words, the owner of this gene is the type of womanizer, playboy. On the contrary, people with the gene that causes irritability and irritation (MSRA gene) will have sex at a later age than average.

But there is a surprising benefit to being easily irritated. Researchers have found that fruit flies carrying the gene reproduce later but live longer than those who mate early.

In addition, the timing of a person's first sexual experience, as well as the birth of their first child, can be related to their performance at school, personal health (diseases such as diabetes, heart disease or cancer). Researchers from the Medical Research Council and the University of Cambridge (UK) analyzed the role of genes in human sexual behavior, a factor that they say has been overshadowed for too long by other factors such as economic conditions, family stability, parental involvement and religion.

Their report states: "The gene that determines hair color and freckles predicts that its owner will remain a virgin until a relatively late age (in women). At the same time, the gene that causes red hair has a similar effect, but this time it is true for both men and women." The study also found that the average age for first intercourse in the UK is 18, and the age at which the first child is born is 25.

Dr John Perry, a geneticist at the Medical Research Council and lead author of the study, estimates that DNA's influence on human sexual behavior is about 25%. The remaining 75% is due to social and cultural factors. "The findings about genes that determine risk-taking and vulnerability in humans are completely new," he said.

As for the conclusion that sensitivity and irritability make people less attractive, Mr. Perry said that "it is completely understandable that personality determines someone's level of attractiveness. While cultural and social factors are obviously involved, we cannot deny the influence of genes. It is an innate mechanism in each of our personalities."
