Love of lightning is also genetic

According to a new study, love of lightning actually exists, at least in terms of genetics.

In a study conducted in fruit flies (but very significant for humans), scientists found that females could perceive which males are genetically more suitable for them, and could reproduce. more eggs after mating than when females mate with other less suitable males. The study's findings show that children have somehow evaluated potential partners right from their first meeting and reacted to promoting opportunities to produce successful offspring.

The researchers mated fruit flies with males of the same species and with other males; They then record the differences in reproductive characteristics and behavior right after mating. When females mate with males of different species, they can learn that these males are genetically more suitable. Perhaps because their descendants will be less likely to cross-line, they lay more eggs and have more children.

It seems that children can sense which males are closely related to them, which is a good cause of genetic defects, while females also react more strongly to capable males. production of descendants is stronger.

Cornell University research co-author Andrew Clark said: 'You can call it love from the first encounter. This view is probably the most accurate because we don't really understand why this meeting changes their response. ' He further explained that not only does the meeting, the look, or the scent, the sound or the senses warn the children that its biologically appropriate partner is near.

Scientists found that female flies seem to be in pre-signaled state even before meeting males, when the chemicals and proteins needed for reflexes are available without having to click. adding new genes as they predicted.

Clark said: 'The main point of signaling is that even if the female does not see the male, her body is ready for the necessary proteins. It was started to love. Therefore, reactions to different males may be different because of this signaling status. '

Researchers believe that mating behavior in fruit flies and humans is very different, so it is difficult to extend these findings to humans even though women may feel that a man is fit about Genetic face to them. The female body can also reflect in a way that increases the chance of successful sexual intercourse.

Clark said: 'In mammals, including humans, the answer seems to be' yes'. The success of pregnancy has affirmed women's feelings for men, which is also the result of the genetic quality of males'.

He described an experiment about very famous T-shirts in humans. People seem to have a tendency to like the smell of T-shirts that belong to individuals who don't seem to correspond genetically to them, maybe that's how our bodies prevent close intercourse.

The main author Mariana Wolfner, professor of developmental biology at Cornell University, said: 'We also observed that males of different species often succeed in giving birth to females for females in both species. fruit flies in the experiment. We can imagine that this happens in any species if a male produces more sperm, or its sperm may be able to reach or fertilize an egg better, or it There may be many proteins in semen that can interact better with your partner's physiological characteristics. But I have not found any concrete evidence of this in humans. '

The study is published in detail in the April 2009 issue of GENETICS magazine.
