To calculate the possible appearance of the future of the child will help the science of genetics. For example, the brown-eyed parent may be born baby with light eyes, and blame is not a neighbor, and a recessive gene. Naregatsi is a dominant trait, which blocks the action of a recessive gene, but that is not going away. If both the mother and the father have recessive genes for light eyes, then at the time of conception they can meet, and the baby will be blue-eyed. Of course, the probability of this is low, only 25%. In all other cases, the couple will be born a brown-eyed child. Examine the color of the eyes of your parents, grandparents, uncles and aunts. If some of them have light eyes, so the probability that parents have the gene, there is.

In respect of hair are the same situation. Dark and curly hair dominates straight and bright, so the probability of the birth of the curly dark-haired child's mom is blonde and dad is brunette, is much higher than the appearance of blonde crumbs.

The weight of the child only 40% is caused by heredity, and by 60% by lifestyle and environmental factors. Therefore, parents tend to be overweight, do not worry for your child, but it is necessary from childhood to teach him to lead an active lifestyle and eat healthy food.

The growth of the child depends on the growth of his parents. As a rule, children have a high vapor grow high, and people below average height is low. Of course, the growth of the baby is also affected by environment and nutrition.

Not always genetics can predict the appearance of the child. Sometimes nature makes jokes, and blonde a few generations of parents may receive a ginger kid. From genetic mutations, no one is safe, and unusual hair color or the eye is most of them are harmless.
