With absolute accuracy, no one can answer the question of what color eyes and what nose the new person will have, just as they can predict how healthy they will be born, but scientists have discovered regularities in the transmission of the genetic code and it is important to know about them – preferably before conception.
The first group, which is reasonably ordered by nature, is responsible for maintaining the “healthy” characteristics of the human population. We are talking about high-quality vision, absence of cataracts, normal hearing, number of fingers and their length, skin and hair pigmentation. But among other things, the list also includes abundant body hair and premature graying. And also a gap between the teeth and a tendency to caries. So if you want your child not to run to the dentist, choose a partner with a beautiful smile. Body type If the husband is a basketball player, short men are unlikely to appear in the family. According to statistics, 70% of a child’s growth is due to the father. If the mother is petite, her genetics will smooth out the proportions.
Dark color, density, curly hair – all these are dominant signs, as well as male pattern baldness. This is why most people believe that the hair loss gene is inherited from the fathers.
Scientists have discovered that the “traveler gene” DRD4 7R is responsible for risk and adventurism. There are one fifth of such people on the planet. Since wanderlust more often takes hold of men, it is passed on to the next generation of them. It turns out that the maternal instinct, the manifestation of care and tenderness are not developed in 8% of women. Intelligence Western scientists already in the 1980s came to the conclusion that the mother transmits mental abilities to the child through the X chromosome, and the closer her spiritual connection with her son or daughter, the higher the intelligence. However, the opinions of researchers differ regarding the percentage of innate and acquired intelligence, someone gives 40% to genetics, someone all 80%. But both have no doubt: intelligence is influenced by a combination of factors – living conditions, the desire for self-development and even the quality of food (including foods rich in vitamin B9), but not by upbringing.
Genes are responsible not only for appearance, temperament, character, but also for physiology. Disability due to hereditary diseases reaches almost half – 47%. Ideally, every future couple, before thinking about having a baby, should get a DNA test for common abnormalities. Both parents can transmit to the child a predisposition to hypertension, oncology, diabetes, allergies and cardiovascular diseases. From the father – the boy has problems in the reproductive function.
The male Y chromosome is responsible for the insufficient number of spermatozoa, their lack of motility and the absence of ducts. Bad genetics is the cause of infertility in men in 30-60% of cases, in women – in 10%. Maternal inheritance of genetic diseases are the most severe forms of damage to the central nervous system, organs of vision, heart, muscles: Martin-Bell syndrome, Duchenne-Becker myopathy, hemophilia, color blindness, autism, ichthyosis, etc.
