How powerful and important human genes are.

Why are some babies born white and some with dark skin? Since the baby is still in the belly, parents will start thinking about what can make the baby's skin white and tender ~ However, 7 minutes is doomed, so don't worry. Basically, if both parents have dark skin, the baby will also have dark skin. And if one side of the skin is white, the baby may inherit this good gene. However, the vast majority of babies have neutral skin color, so-called black, which is only white compared with parents' expectations.

Double eyelid VS single eyelid

This is about the inheritance of dominant genes and recessive genes. Double eyelids are dominant genes, while single eyelids are recessive genes.

As long as one of the parents has double eyelids, the probability of a baby's double eyelids can reach almost 90%, but there is still the possibility of a single eyelid. This is because both parents have the genetic factor of single eyelid. When the genetic factors of single eyelid carried by both parties form a pair, the baby is a single eyelid.

So if both parents have single eyelids, will they give birth to a baby with double eyelids? I will! This may also be recessive inheritance and atavism. Moreover, some babies have not grown up when they are young, and when they grow up, their single eyelids become double eyelids.

Chin and dimples

This is also dominant inheritance. If mom and dad have prominent chins or dimples, the baby will generally inherit.

nose

It is also dominant inheritance. As long as one of the parents has a big nose and a high nose, the baby is likely to inherit this advantage in the future. Moreover, it is said that the inheritance of the nose will last until the baby reaches adulthood. Even if it is a flat nose when I was a child, it may become a tall nose when I grow up.

fat

Some people say that I was born to eat fat; Some people say that my obesity is hereditary and I can't help it. Can that chubby physique really be inherited?

According to research, this is indeed related to the genetic factors of body shape. If parents are easy to gain weight, children are also easy to gain weight. If one parent is obese, the probability of children being obese is 30%; If both parents are obese, the chances of children getting fat are 50%. Except that very, very fat is inherited, most of them are acquired! In the concept of elders, the baby is chubby, cute and well-fed. Coupled with all kinds of junk food, many babies are now chubby since childhood. This requires parents to pay attention to the baby's reasonable diet and nutrition and exercise in daily life!

height

70% of a child's height is in the hands of his parents. The inheritance of parents is the main factor that determines his height, because 35% of the factors that determine his height come from his father and 35% from his mother. If the parents are not tall, it depends on the baby's 30% efforts the day after tomorrow. Such as adequate sleep, reasonable diet and nutrition, staying away from junk food and strengthening exercise.

sight

Can parents myopia baby be nearsighted? Many parents have this concern. According to research, the probability that parents' myopia is passed on to their babies is only 5%. On the contrary, many parents are not nearsighted, but many children are nearsighted since childhood. This is indeed related to the habit of using eyes, especially now children like to play with electronic products such as ipad and mobile phone, which is particularly harmful to their eyes.
