What is the relationship between genetics and longevity? Is lifespan genetic?

Is lifespan genetic? Yes, for sure! For example, if some diseases are inherited, the life expectancy is relatively low, and if there are no genetic diseases, the life expectancy is relatively high. "Inherited traits determine a person's lifespan". This is a famous quote from the famous geneticist Morgan.

Life expectancy is closely related to heredity, the international standard of 80 years old as the longevity of the elderly, as early as the beginning of the last century, scientists have found that more than 80 years old in the descendants of a certain family, more than half of their parents have reached 80 years old, thus confirming that the life expectancy of people is related to heredity.

The American Pole examined a centenarian and found that the average life expectancy of his six direct ancestors was close to 100 years.

Therefore, some people have proposed that the life expectancy of a person can be increased by the average life expectancy of 6 parents, grandparents and maternal grandparents, and a large number of surveys and studies have confirmed that this law has a certain reference value.

Professor Li Tiejun of Nanjing University of Traditional Chinese Medicine and others spent one year on 100 long-lived elderly people in Nanjing (including the highest age of 107 years old, the lowest age of 93 years old, and 42 people over 100 years old) to conduct a survey and research on the average longevity of the elderly, the average life expectancy of the long-lived elderly is the age of the year, the average life expectancy of the elderly is only about 35 years old before the founding of New China, and the life expectancy of the parents of these birthday stars is almost twice the average life expectancy at that time.

Therefore, it can be said that genetics are an important factor in determining lifespan. The general elderly are about 85 years old, and even if they do not suffer from fatal diseases, they will face the threat of old death, while centenarians are much slower than ordinary people. Jiang Ning Ni Peiying, who lived to be 107 years old, could still go up the mountain to chop firewood at the age of 90, and could do some light work at the age of 100.

According to a 1999 statistical analysis of 116 centenarians in Shanghai, it was found that more than 40% of their families had longevity genetic factors.

Summary: Genes are embedded in chromosomes, and chromosome studies on long-lived elderly people have shown that the chromosomal aberration rate of long-lived elderly people is lower than that of the general elderly, and the proportion of sex chromosome loss is also lower.

Lifespan largely depends on genetics, and longevity genes in the body can affect lifespan, but lifespan is also related to the external environment, so lifespan is the result of the combined action of genes and environment.

It's not just genetic, there are many influencing factors. Genetics can affect one's lifespan, but a good routine can also prolong one's lifespan.

Inherited genes may affect the length of lifespan, and lifespan is not completely inherited and affected by acquired habits.

Heredity and longevity have nothing to do with each other. Lifespan cannot be inherited because heredity does not lead to a reduction in lifespan.

Wang Chong proposed the use of the equivalent of what is now said "eugenics.""Methods to change genetic factors, so that their children are endowed with the strength of their parents and achieve the goal of longevity.

The First Gentleman of Life Extension uses the method of mate selection to change genetic factors.

Traditional Chinese medicine has the theory of acquired congenital nourishment, that is, congenital inheritance is not good, and it can be changed by acquired imitation and consumption. "Health Skin" also said: "Longevity is in the ,...... of the father."But the cultivation of harmony and virtue is up to oneself at the moment.

Therefore, as long as you pay attention to your health, you can expect to live a long life even if your parents have a short lifespan. For example, Yu Minde, a native of Dinghai in the Ming Dynasty, died early when his parents died early, and when he grew up, he planted bamboo and wood around his place of residence, paying attention to nurturing, but he lived to 105 years old.

A significant proportion of today's centenarians are also linked to genetic factors.

According to the Hubei survey, 88 centenarians have a family history of longevity. Among rural centenarians, genetic factors are particularly prominent.

Liu Zhang, a centenarian in Zhouba Township, Muchuan County, Sichuan, is also a family with three generations of longevity, his mother died at the age of 102, the eldest sister lived to be 103 years old, and her daughter is nearly 80 years old and healthy.

Ma Duoze, a Hui centenarian on the Qinghai Plateau, has five generations in the same house, her mother died when she was over 100 years old, and her eldest son and eldest daughter are also ancient old people.

It is important to note that genetics is not an absolute factor in longevity

The same is born to long-lived parents, not all siblings are long-lived, and even some parents are long-lived, and the children born are short-lived, which has more to do with their own rearing.

Studies have shown that healthy longevity is made up of 5 factors: parental genetics 15%, social environment 10%, natural environment 7%, medical conditions and personal lifestyle 60%. The first three items were uncontrollable cause fibrillation, accounting for 32% in total; Of the 68% controllable factors, the individual's lifestyle is close to ninety percent, so life is in one's own hands.

As the saying goes, a person's hair and skin are his parents. Indeed, the longevity of a child has an important relationship with the parents. Judging from the current research results on human life sciences, genetics are still the main factor in the length of human lifespan.

So, who has the most to do with the longevity of a child?

1. From the perspective of genetics, lifespan is also determined by genes, and there are differences in the proportion of genes from parents. It is said that the lifespan of a father affects the son more, while the lifespan of the mother has an impact on both the son and the daughter.

2. Judging from most examples in life, generally in terms of physical signs, sons follow their mothers more, and daughters follow their fathers more. For example, there are two sons and one daughter in a family, the father has high blood pressure, and the mother has normal blood pressure. In the future, the probability of the daughter suffering from high blood pressure will be higher, while the son will generally not.

Similarly, the family has two sons and a daughter, the mother is nearsighted, and the father has normal vision. In the future, the probability of myopia of the two sons is very high, and the daughters generally do not. And so on and so forth, and so on, and so on.

So heredity is very subtle and regular. Of course, nothing is absolute.

In addition to congenital physical fitness, long-lived people must also have acquired exercise and maintenance. People who live a long life also need to maintain a peaceful mind, and emotional movement is also easy to cause diseases and wear out the body. If you want your child to live longer, you should take care of your husband's and wife's body when you are preparing for pregnancy, get pregnant in the best state, and follow the doctor's instructions to take care of the mother's body during pregnancy to ensure the nutritional supply of the child.

If a child happens to inherit a disease gene from one of their parents, it is likely to affect their lifespan. There are many factors that affect longevity, and there are many, many genetic reasons, so it cannot be said that it has more to do with anyone, but it should be said that it has a certain relationship with everyone.

I think there is a certain relationship, but it should not be much. In real life, we are often told that if there is a father, there must be a son, and if there is a mother, there must be a daughter. This quote not only says that the character of the child will follow the parents, but also in many other ways like the parents. That's the power of heredity.

Since the parent's marker will be passed on to the child along with the chromosomes, does inheritance actually inherit the parent's marker? Can you use life as an example?

In fact, the child's life is actually inherited by the parents, not both parents. Father or mother? What are some factors that determine who will follow their parents in life?

Recent studies have shown that certain genetic variations in mitochondria affect the longevity of offspring, and since the mitochondrial genome is inherited only in the maternal line, life expectancy is more influenced by maternal inheritance. In other words, if a person's mother is longer, then the person will live longer. Since the mitochondrial genome, which is inherited from the mother, influences the genes of aging, the child's life is also closely related to the mother's life.

Scientists have conducted experiments on animals and found that certain genetic mutations are induced in the mitochondrial DNA of female mice. The average lifespan of their offspring is about 45 weeks, which is about 10 weeks shorter than the average lifespan of normal female offspring. In addition, these genetically defective rats also exhibit symptoms of accelerated aging, such as brain damage and motor dysfunction.

The researchers explained that mitochondria are the "power plants" of the cell, providing energy and a place for cellular life activities.

This has a certain relationship, but it is closely related to your acquired situation.

This is related, but most of it depends on one's acquired behavior.

It may be a congenital disease, it is possible, but the acquired most important.

This thing actually has something to do with it. But there's still a big part of it about yourself.
