What is the function of genes?

The function of genes is:

1, biological functions, such as phosphorylation of specific proteins as protein kinases;

2. Cytological functions, such as participating in intercellular and intracellular signal transmission pathways;

3. Developmental functions, such as participation in morphogenesis.

Genes support the basic structure and expression of life. It stores all the information about race, blood type, gestation, growth and apoptosis of life. The interdependence of environment and heredity deduces important physiological processes such as life reproduction, cell division and protein synthesis.

All life phenomena such as birth, growth, decline, illness, old age and death of organisms are related to genes. It is also an internal factor that determines the health of life. Therefore, genes have dual attributes: materiality (mode of existence) and information (fundamental attribute).

Five genetic characteristics that the extended data will pass on to children:

1 Life

Life span has a genetic basis. Some families live long, but others are short-lived. The length of life has a tendency of family gathering. If there is a precedent of longevity in the family, then there is a great possibility that children will live long. For twins aged 60-75, the average time difference between male twins and female twins is 4 years, only 2 years.

However, life expectancy will also be affected by environmental factors, such as eating habits, living environment, working environment, etc. These factors will also affect people's life expectancy to varying degrees.

2. Eyes

Shape: The shape of parents' eyes has obvious influence on children. For children, eye shape and eye size are inherited from parents, and big eyes are dominant over small eyes. As long as one parent has big eyes, it is more likely to give birth to a child with big eyes.

3. Skin color

Skin color is often genetically impartial, leaving people with no choice. It always follows the natural law of "average after multiplication" and gives children the brand of "comprehensive color" of their parents. For example, parents have dark skin, which is definitely not for children who will not have white and tender skin; If one parent is black and the other is white, then after "averaging" in the embryo, a neutral skin color that is neither black nor white will be formed for the child.

Therefore, the child born to the yellow race must be the skin color of the yellow race. An African student found a China woman with dark skin, and her child was born with dark skin.

4. Fat and thin

People's figure has certain heredity. People think that different people have different metabolic rates. Generally, people with low metabolic rate tend to get fat, which is determined by the genetic factors of body shape. If parents are easy to gain weight, children are also easy to gain weight. Therefore, such children should pay attention to balanced nutrition after birth and don't eat too much.

If one of the parents is obese, the probability of the child being obese is 30%. If both parents are obese, the child has a 50%-60% chance of getting fat. In addition, there are also some sayings that mothers play a greater role in children's body shape, that is to say, children are more like mothers regardless of gender.

5. Height

Research shows that 70% of people's height depends on heredity, and the influence of acquired factors only accounts for 30%. Generally speaking, if parents are tall, the probability of children being tall is 3, the probability of being short is 1, and the probability of being short is just the opposite. If one parent is taller and the other is lower, it depends on other factors.
