Big chin is inherited

As Chinese, or Asians, we tend to have smaller faces, but some people have particularly large, square chins, which look very much like foreigners' faces. This may be inherited to a certain extent, because a child's birth is based on the appearance of his parents. So whether it is inherited and what the inherited appearance will be depends on the test results.

Real case: Women with smaller chins are more attractive

This research result from the State University of Nebraska was recently published in an American magazine. The researchers also found that women with smaller chins were more attractive. Women with smaller noses, wider eyes and smaller mouths are also more popular.

Scientific explanation: It is absolutely a dominant trait. If either parent has a prominent large chin, the child will most likely grow a similar chin. This trait is very obvious.

sound

Real case: The left brain can identify the voices that are important to you

Why can people recognize the voices of their lovers or children amidst noise and crowds? A research team recently discovered that this is because the auditory area of ​​the left brain is able to distinguish sounds that are important to the individual. [detailed]

Scientific explanation: A child’s voice is usually very similar to that of his or her parents, even more so than in appearance or body shape. If the father has a hearty laugh and the mother has a loud voice, it is hard to imagine that the child will speak softly. Usually, a son's voice is very similar to his father's, while a daughter's voice is very similar to her mother's.

The pitch, volume, and sound quality of the voice are not only related to the larynx, but are also determined by factors such as the size of the nose, the size of the mouth, the length of the tongue, the bones of the face, etc. Moreover, all of these aspects are inherited from the genes of the parents, so it is not surprising that voice is inherited. However, if the sound quality influenced by the parents' physiological and anatomical structure is not beautiful, most of it can be changed through acquired pronunciation training. Therefore, some people whose vocal conditions are not favorable may experience voice changes through acquired pronunciation training. In this way, people who do not have good vocal conditions can realize their dream of having a sweet and mellow voice through scientific and hard practice.

intelligence

Real case: A baby's IQ depends on a special gene

The latest research shows that a baby's IQ does not depend entirely on breastfeeding, but the key lies in whether the baby carries a special gene. The study also showed that only one in ten babies carries the gene. [detailed]

Scientific explanation: Although intelligence is not entirely determined by genetic factors, it does have a certain relationship with genetics. Human intelligence depends on both genetic and environmental factors. It is generally believed that genetics plays a large role, while the environment determines the other 40%. Someone has conducted a long-term study on a group of children with an IQ of more than 140 points, and found that these children maintained excellent talents when they grew up. The average IQ of their children was 128 points, far exceeding the level of ordinary children. Among those with mental disabilities, 59% of their children have mental disabilities or intellectual disabilities.

The inheritance of intelligence includes not only IQ but also EQ. The so-called emotional intelligence refers to a person's personality, temper, ability to deal with things, communication skills and other aspects. For example, some children are like their fathers in terms of their ability to deal with things and socialize, but in other aspects, such as personality and temper, they are very similar to their mothers.

In addition, a child’s intelligence is also closely related to the environment, and the actual performance of intelligence is greatly influenced by acquired factors, so we advocate early education. Starting from the fetus, the first peak of brain cell development occurs at 10-18 weeks, and the second peak occurs 3-6 months after the child is born. If you want your child to have good intellectual development, you should pay attention to nutrition intake during the first peak period, i.e., pregnancy, and breastfeeding during the second peak period. This will enable your child's intelligence to develop well.
