Which genes are passed from child to mother and which from the Pope: you will be surprised

I think you heard the phrase "all in the mother" or "father in the whole." Scientists say that this is a false statement. Each parent passes on a child half his genes. But his father's genes are more aggressive than my mother, so they are becoming increasingly dominant, that is manifested.

sex of the child

For half a baby sperm meet. Ovum always carry a "girly" X-chromosome, and sperm - or the same X-chromosome (then the child will be female) or Y-chromosome (and then a boy). Scientists have noticed another fact, if my dad a lot of brothers, the probability of his son's birth increases if it has many sisters, the more daughters will be born. Few men contain almost the same number of sperm with the X and Y chromosomes.

external signs

In the male Y-chromosome contains fewer genes than the X-chromosome. Moreover, a certain amount of Y-chromosome is responsible for the formation of male sexual characteristics. Therefore, most of the exterior of the children receive from his mother. In the case of birth of a girl, she gets the same number of genes from both parents, so her appearance to guess in advance will not work.

dental health

Although the structure of the jaw and the shape of the teeth can transfer both parents, for the health of your teeth is responsible dad. So if he frequently visits the dentist, and the children will be in a dental clinic frequent "guests".

Mind

Sons intelligence transmit their mother. Daughters inherit the mind and of the pope, and from my mother. But only 40% of intelligence is genetically transmitted, the remaining 60% - depend on education and training. So no matter how smart parents were not, if their children will develop the intelligence they have appropriate.

The tendency to mental illness

The older a dad is, the worse than his sperm and a set of genes in the sperm. This factor increases a child's risk of developing mental disorders. Scientists have found that children born to fathers aged 45 years and older are more likely to commit suicide, and problems with learning.

Propensity to disease

Pope with coronary heart disease can pass it on to his sons. Infertile men who decided on IVF, transmit son predisposition to this problem. Hemophilia (poor blood clotting), Duchenne muscular dystrophy (progressive muscle dystrophy), autism is most often transmitted Women sons. In this case, even if the mother carries the defective gene responsible for these diseases, they may not appear in daughters. The fact that his son is transmitted only one X chromosome from the mother, the girls - two from each parent. Therefore sons nothing to replace the bad gene.

Height and weight

Almost 40% of people propensity to be overweight or thinness is transmitted from parents. Moreover, it can be like Mama's "heritage" and Papa's. Here are just a predisposition to harmony rarely passed on to children, than a tendency to gain weight.

From 60 to 80% child growth determine the genes of his parents. The rest depends on lifestyle and nutrition. The scientists also noted that when growth is about the same parents, their younger children are less senior. Find out the baby's growth in the future you can in two formulas.

Formula 1. Boy Height: to add Pope mom growth growth, and then another 13 cm, divide the total by 2 - it is about the growth of your son in the future. The growth of girls: a mom growth of the pope add growth and subtract 13 cm, divide the result by 2 - it is about the growth of your daughter.
Formula 2. The growth of girls in 18 months and a boy - are multiplied by 2 years to 2. About this growth, plus or minus 10 cm and will be at your child when he becomes an adult.

eyes color

Brown eyes often dominate. But, you may receive the child and with light eyes, if the brown-eyed parents have a recessive gene for light eyes. At the same time there is the appearance of brown-eyed baby in two blue-eyed parents and vice versa.

Dimples

If one of the parents has dimples, the more likely that they too will be in the child. It's just a dominant trait.

Curly or straight hair

If both parents have curls, then the child is likely to be born curly. If straight hair in both parents, the child they are straight. Straight hair can be a child if both parents of recessive genes have straight hair. If one parent is curly, the hair can be wavy.

How to predict the appearance of the baby?

Every family has dominant genes. For example, all members of the family bulbous nose, or full lips, probably this gene will dominate your baby. Look closely at pictures of her husband and his relatives, so you can understand about what features can be your baby.
