How to find out what the future child will look like
On which of the parents will look like a baby, decidesgenetics, operating with dominant (leading) and recessive (driven) genes. The result is a genetic cocktail, prepared by the joint efforts of both parents. In fact, the similarity to dad and mother is not accidental, it is inherent in nature for the early activation of maternal and paternal instincts.

The sex of the child depends entirely on the father. In this issue, the main role is played by which of the spermatozoa fertilize the egg. X-chromosomes that program the birth of girls, as much as the Y chromosomes involved in the birth of boys. In fact, little more girls are born to boys, in view of their low resistance to disease.

Trying to predict the color of your eyes, remember thatThe gene that is responsible for the brown eyes is dominant. If one of the parents has blue eyes, and the second - brown, most likely, a strong gene will win and the kid will be dark-eyed. However, if this rule did not allow exceptions, the entire population of the planet would become more or less monotonous long ago. But nature, having thought out all the details beforehand, ordered differently. It turns out that the owners of dark eyes sometimes have light-eyed children. This is possible, if at least one of the relatives (even in the previous generation) was blue-eyed, green-eyed or gray-eyed.

Blond hair is also a recessive sign. When both parents are blonde, child inherits the same color. If the father or mother will give him the dominant gene of dark hair, the heir will have every chance to adopt it. In principle, it is possible to merge the shades of parental hair. As for the structure of the hair, the baby is more likely to inherit curls (or wavy hair), of course, if one of the parents has this characteristic.

By inheritance, and a dimple on the chin,and prominent ears of one of the parents. Scientists came to the conclusion that a large nose with a hump should also be classified as a dominant feature.

Most likely, the baby will inherit short-haired, as well as the sixth finger, if they are endowed with one of the parents, of course.

In the issue of the future growth of a child it is difficult to doforecasts. As a rule, he stops at the average arithmetic between father's and mother's growth. But this is in conditions of proper and adequate nutrition, as well as depending on the diseases. At the same time, if the kid has an enviable appetite, moves a lot, sleeps the right time and eats properly - he has all the chances to outgrow his short parents.

In general, boys are much more like mothers. This is explained by the fact that they inherit only one single X chromosome, which is rich in genes of appearance. In girls, the situation is different: they get an equal number of such genes from both mom and dad. Accordingly, a girl can be like both parents with equal probability.
