Why Mickey Mouse chose Minnie
First, a fascinating conclusion, then boring explanations and details. So: the more you like the smell of sweat of your sexual partner, the healthier your children will be - proved by science.
This story began in the first half of the 1970s, when biologist J. Boys (I could not find the full name, so I don’t even know if he was a man or a woman) was engaged in a routine genetic work: he crossed mice to get a clean line, in which all animals would have a gene complex called AKR-H-2b. Usually this problem is solved easily, but it was in the case of this gene complex that oddities began: the males who inherited the AKR-H-2b genes from both parents absolutely did not want to interbreed with the same females, and with the slightest possibility of choice, they strongly chose other AKR-H-2k Boys, apparently, then still forced the animals to mate with someone they give and not to buzz, but he remembered that such a problem exists for some reason.
Meanwhile, another biologist, L. Thomas, reflects on this complex of genes, and suggests that the H-2 genes (as they are called in mice, and the common name is “the main histocompatibility complex”) can affect the smell of an animal and provide individual differences in it. Boys reads Thomas’s reasoning, communicates with him, says something like “But I had a chance!”, They get excited about each other and in 1976, together with several other authors, publish the first experimental work on choosing a partner based on individual odor, determined with the participation of genes of the major histocompatibility complex23. From the moment of the publication of the article in the studies of this important complex of genes, a new branch appears that is taught to students under the code name “As scientists have noticed that mice have love”.
The essence of this historical experiment is as follows.
