"Papa inheritance", or that children inherit only from their fathers?

Genetics - an interesting thing. Here, it would seem, if the baby gets 23 chromosomes from the mother and 23 from the father, hence the genetic influence on the formation of the child shall be equivalent? En-no, it turns out, and it is proved by scientists from the University of Carolina Server. Scientists have crossed the three groups of mice, resulting in mice born nine types.

An-no, it turns out, and it is proved by scientists from the University of Carolina Server. Scientists have crossed the three groups of mice, resulting in mice born nine types. When they grew up, it was evaluated the degree of gene expression, and it turned out that from parents genes appear uneven expression ratio: 60% of paternal genes and 40% of the parent, that is, the father's genes stronger parent, and children are actively inherit, and as a result exhibit precisely the father's genes. Today we offer you some information about the daddy's genes.

The struggle in the embryo level

A scientist from Harvard, David Haig proved that maternal and paternal genes manifest themselves differently already in the embryo. Paternal genes (sometimes even to the detriment of the health of the mother) are forcing the fruit to extract the maximum amount of nutrients and energy from the mother, the father's genes have "a vested interest" in the fact that the child receives as many parent resources and fighting for their very aggressively. And yet, scientists from Cornell University concluded that such a unique and exclusively female organ, the placenta, built thanks to his father's genes.

Genetic mutations

The researchers also found that the most important mutations occur under the influence of precisely the paternal and maternal genes do not. Therefore, inherited from the father's gene mutation manifested in the child more quickly than mutation, inherited from his mother. That is, if the child has received a "diseased" gene from his mother, he is likely to be manifested not as active as a gene, resulting in the inheritance from his father.

Gender Child

Only the pope can influence the sex of the baby. You probably remember from school biology course that babies gets the combination of chromosomes from both parents - the X chromosome from his mother and XY-chromosome from her father. And if a girl or a boy is born, it depends on what kind of father's cell merged with the parent. If there is a merger of the paternal X chromosome from the mother's egg - a girl, if the Y - a boy. As they say. Pope COX, and that no options.

Intelligent genes

And here the husband, daddy - the level of intelligence, as evidenced by the results of scientific research, mainly determined by the maternal genes. That is, the dads are less likely to pass on the genes responsible for the intelligence of the child, for the genes that are responsible for the mental faculties are connected to the X chromosome, which women exists in two "copies", while for men the same. So if you decide to have a future Nobel Prize winner, you need to look no dad and mom with super-brains, because scientists have even suggested that received from the Pope still alive Nobel laureate genes can automatically "deactivated" the heir.

Problem genes

Unfortunately, Pope transmitted successors not only, for example, stunning red hair or manly chin and perfectly shaped nose, but also a tendency to heart disease (which mainly concerns sons), curved teeth (and comfort in this case may only that if my mother's teeth need braces, and the Pope Hollywood smile, the child is unlikely to need a dentist). And if by inheritance, alas, is transferred to infertility, that is, if a man has become a father through IVF, then his son, unfortunately, is also likely to face the problem of infertility. If a man became Pope in advanced age, there is a risk to transfer the child inherited the goods of mental disorders. A similar problem - this is the trouble late paternity, as the DNA of men varies with age, unlike women, whose DNA does not change with age.

The color, height, facial symmetry

All of this is most often determined by paternal genes. And the lovely dimples in the cheeks, the bright red (stinging black, soft wheat) curls, lip shape and sneezing ... the sun - it's all the gifts from the Pope.
