Even during pregnancy, future parents like to assume how their baby will grow up, what character he will have, whether he will strive for the exact sciences, like a dad, or he will have the artistic abilities of a mother. Of course, parents are also interested in the appearance of their child.
The science of genetics will help to calculate the possible appearance of the unborn child. For example, brown-eyed parents may have a baby with bright eyes, and it is not the neighbor who is to blame for this, but the recessive gene. Brown-eyed is a dominant trait that blocks the action of a recessive gene, but it does not go away. If both mom and dad have recessive genes responsible for light eyes, then during 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 have a brown-eyed child. Study the eye color of your parents, grandparents, uncles and aunts. If some of them have light eyes, then there is a possibility that the parents also have this gene.
The same situation occurs with hair. Dark and curly hair dominates over straight and light, so the likelihood of having a curly dark-haired baby in a blonde mom and a brunette dad is much higher than the appearance of a blonde baby.
The weight of a child is only 40% determined by heredity, and 60% by lifestyle and environmental factors. Therefore, parents who are inclined to be overweight should not worry about their child, but from childhood it is worth teaching him to lead an active lifestyle and eat healthy food.
The growth of a child depends on the height of his parents. As a rule, children in tall couples grow tall, and in people below average height, they grow short. Of course, your baby's growth is also influenced by the environment and good nutrition.
Not always geneticists can predict the appearance of a child. Sometimes nature makes jokes, and fair-haired parents in several generations may have a red-haired baby. No one is immune from genetic mutations, and unusual hair or eye color are the most harmless of them.
