We learned which genes are passed to children from dad and some from mom

If you hear a statement like “You’re / all in the mother”, then you know that this is a false statement. In fact, we (especially women) are more like their fathers, not mothers. In addition, there is an assumption that the lifestyle of the father before conception of the child, nutrition and health, lay the Foundation for future health of the baby. What traits are passed to the child from dad and some from mom, read this article.

AdMe.ru recommends remember that even with a good heredity we should not forget about the correct way of life. He ultimately determines how you will look and how to feel.

Most often, children inherit from their parents form the tip of the nose, the area around the lips, the size of the cheekbones, the corners of the eyes and shape of chin. When facial recognition, these areas are key, so people with the same areas seem to us to be strikingly similar and even identical.

But the area between the eyebrows is often different from the parents and their children.

Mom’s genes usually account for 50% of the baby’s DNA and dad’s — the remaining 50 %. But male genes are more aggressive than women, so they often Express themselves. So, 40 % of the active mom’s genes can be 60% of dad’s.

In addition, the pregnant woman’s body recognizes the fetus as a half-alien body. To save the baby, he has to put up with the aggressive paternal genes (sometimes to the detriment of their own).

However, you can determine which characteristics will be passed to the baby from dad and some from mom.

The sex of the baby

The sex of a baby depends on the father. From mom, the child always gets his X chromosome, from dad or also X chromosome (and then it’s a girl) or Y chromosome (and then it will be a boy).

Thus if the men in the family a lot of brothers, then he will have more sons, and if a lot of sisters, respectively, daughters. Only in some men’s semen contains approximately equal the ratio of X – and Y-chromosomes, and they are equally likely to be born both boys and girls.

The Y chromosome contains far fewer genes than the X chromosome, and some of them are responsible for the formation of male sexual organs and the production of spermatozoa. Therefore, features of the appearance of the boy mostly will get from my mother and be like her. As for girls, they will receive X chromosomes from both parents, so anticipate their appearance will not succeed.

The condition of the teeth

If dad’s a pretty frequent guest in dental clinics, it is likely that the child will often visit the dentist. Although the size and shape of the teeth and features of the structure of the jaw can be transmitted from either parent, most dominant are the genes of the father.

So if dad has crooked teeth, then the child is sure to be a malocclusion.


The genes responsible for intelligence are contained in the X chromosome. Therefore, mothers transmit their mental abilities sons. Daughters received mental abilities from both parents. However, inherited only up to 40 % of maternal intelligence, everything else children are the result of education. So work hard on yourself, there is no substitute.

The average IQ in boys differs from the parent for no more than 15 points.

A tendency to mental illness

With age, men have worse sperm quality. Because of this, older people can give to the children of the mutated genes. This increases the risk of the child’s mental illness, autism, hyperactivity, bipolar disorder. Also children born to fathers aged 45 years and older, can be suicidal and have difficulty learning.

At any age, the stronger sex, suffering from coronary heart disease, transmit the tendency to their sons. Men who suffer from infertility, but because the conception was carried out by artificial means, also passed to the son of a predisposition to this problem.

The tendency to hemophilia and autism

There are diseases that are passed from the mother, but are manifested only in boys (in girls, the probability of these diseases is negligible). This happens if the woman is a carrier of the X chromosome with the defective gene and it is this chromosome for his son. Unlike mom, the boy has only one X chromosome, so he has nothing to compensate for the mutated gene.

The diseases transmitted from mother is hemophiliac (bleeding disorder) and Duchenne’s myodystrophy (progressive muscle weakness). Autism is most pronounced when it is passed from mother to son.

The tendency to gain weight

The tendency to gain weight or, conversely, harmony is genetically transmitted. Some people weight and waist width of 25% is due to genetics, in most cases by 40%. People struggling with obesity, these numbers can reach 75-80 %, and then to get rid of extra pounds becomes problematic. Although in this case, a reasonable diet and exercise will result.

The tendency to leanness or obesity is transmitted approximately equally from both parents. The predisposition to slenderness is transmitted to a lesser degree than the tendency to gain weight.

However, on the child’s weight at birth affects only the mother. No matter how large the mass of the father, the baby is born is slim, if the woman is thin. But if the mother is obese, the baby from birth can be “reserve”.


The growth of the child are more affected fathers than mothers. Tall men have children, usually have at birth and higher growth. In General, from 60 to 80% of a child’s growth is determined by its father and mother, and the rest is the result of his power, lifestyle and health. In addition, not all siblings have the same height: as a rule, the younger below the older.

There are 2 formulas for determining the growth of the unborn child.

  • If you have a boy, to the growth of the mother add to the growth of the Pope and then another 13 see, Divide the total by 2 and you will see how high will be your son. If you have a little girl, to increase mother’s add to the growth of dads and subtract 13 cm, Divide the result by 2 and you get the approximate height of your daughter.
  • Note the increase in girls at 18 months and a boy of 2 years and multiply the data by 2. This growth (plus or minus 10 cm) is your child in adulthood.

Eye color

Brown eye color is dominant trait. Therefore, if one of the parents (especially the father) the dark eye and the other blue or green, the child is likely to be brown-eyed. The chance to see blue-eyed baby still remains, but only if the parent with dark eyes have a recessive gene for blue eyes.

Blue and green eyes — recessive traits, but the blue is more dominant than green.

At the same time we cannot exclude the possibility of a brown-eyed baby with blue eyes parents.


Dimples is a dominant trait. If they have at least one parent, then with high probability they will manifest themselves in the child.

Quadravest hair

Curly hair is very beautiful, and a mom’s dream that their child will also be curls. However, despite the fact that the tendency of hair to curl is a dominant trait, the presence of its one parent is not enough.

A simplified version of the schema like this:

  • If both parents have curly hair, then the child will have curly hair.
  • If mom and dad’s straight hair, then the baby will be straight.
  • If one of the parents — curls and the other straight hair, then their offspring will have wavy hair.

However, if both parents have the curls, but in the family they were people with straight hair, it can happen that the child’s hair will be straight.

Bonus: how to predict what looks will be the baby

View family photos of both parents. Pay attention to what traits consistently repeated in the majority of relatives (hooked nose, curly hair, dark eye color). These traits are dominant and with a high probability they will occur and your child.

Which of your parents do you look like? Maybe your child has surprised you with an unexpected eye color or curly hair? Tell us about it.
