Genes and chromosomes transmitted to the child

So, for heredity, there are chains in the DNA molecule, called "genes." Mixing the genes of mom and dad from the point of view of biology can be considered a unique genetic experiment. This name is the process of the birth of a new life and gave one of the leading experts in the field of genetics behavior American Robert Plomin. In biology, the sacrament of conception can be written in the form of a certain formula, like the genes and chromosomes transmitted to the child: each egg and each spermatozoon carries a unique combination of 23 chromosomes. Uniting in pairs, at random, the parent chromosomes form the unique genetic code of the future person - the genotype.

Fact

Babies are more like dads. Nature "conceived" so that the man immediately saw in the child himself and the instinct of paternity formed faster.


To mom or dad?

The child, as a rule, inherits the color of the eyes of that of the parents, from whom they are darker. For example, a brown-eyed mother and a blue-eyed father, even if the baby is Papa's copy, eyes will most likely be brown.

If one of the parents has curly hair, then the first child, most likely, will also have curls.

The first child is a boy? Then he certainly will be like a mother with the help of the gene and the chromosomes passed on to the child. The girl is for dad. In such cases, they say: "It will be happy."

The mind and ingenuity of the crumb inherit from the mother. The latter, by the way, is confirmed by science. The fact is that the genes "responsible" for IQ are in the X chromosomes, which the woman has two (XX), and the men have one (XY).

Born from a brilliant father, the girl has a much better chance of being known as a clever clever woman, but on the son of a genius person, nature is likely to "rest".

Svetlogolovym "in mum" the kid will be only in the event that blondes were and among relatives of the father.

Harmful habits are coded at the genetic level. Alcohol dependence is determined by the gene responsible for the synthesis of the enzyme that cleaves the alcohol. If the gene is mutated, then the child of parents who love to drink, has a tendency to alcoholism.


Character by inheritance

The fact that the character is inherited through the gene and chromosomes passed on to the child has not yet been scientifically confirmed. Although the "aggression gene" discovered by scientists a few years ago has already given the ground for such kind of conversations. True, practical experiments have refuted them. And yet, it's not for nothing that Russian rumors advised, choosing their wife, to look at the mother-in-law. How many times have you already said, looking at the daughter: "Well, stubborn - all in the grandfather!" Or noticed in the son: "Oh, the character is the father's." Yes, all this can be attributed to the so-called costs of upbringing. The fact that the child unconsciously copies the behavior of the parents, noticing how they behave in a particular situation. Then he repeats the act in similar conditions. Meanwhile, scientists working on deciphering a person's genetic code have already established that the propensity for polite or rude behavior is 34% inherent in us genetically. The rest is determined by education and environment. And even the choice of profession, we are 40% obliged to a certain combination of chromosomes. At least, leadership qualities in most cases are inherited. Perhaps, that is why in Russia there was a dynastic principle of the transfer of royal power - from father to son.


"No mother, no father ..."

Indeed, it happens that a son or daughter is not at all like their parents. They can easily repeat the genotype of some distant relative. Or very distant. And for a long time already left this world.

A similarity to someone often worries his father very much. Tell your beloved husband that your child is like your great-great-grandmother or - and he will calm down for a while.

And also revise the children's photos of her husband, her own and you'll see: the appearance of an adult child changes constantly and after a year or two your crumbs may manifest many of your features.

Geneticist and Ph.D., Dean Heimer, first stated the existence of the "homosexual gene" in 1993, and in 2004 he wrote a book about the discovery of the "gene of faith in God."

British scientists analyzed the character of 609 pairs of twins and it turned out that if the abilities to conduct one's own business, sociability and introvertedness were peculiar to one of the brothers, then they were necessarily present in the character of the other. Even such a habit as the desire to sit for a long time in front of the TV, 45% inherited. And about the "gene of genius" and the possibility of its isolation, and even its implantation, scientists have long argued seriously in the genotype of a particular person. In this case, the subject of the dispute is the moral component of the issue, and not scientific hypotheses. As Sherlock Holmes once said, looking at the portraits of the Baskerville dynasty: "Now do not believe after this in the transmigration of souls!"


Black, and striped

In the 19th century, telegonia was popular. The theory that the appearance of the crumbs is answered not by the father's genes, but by the mother's first partner. It arose after a case in the world of horses.

One breeder decided to cross a zebra with a mare. She did not want to produce offspring from a stranger. Then the foals were born with a zebra strip.
