Are parents and children suitable for marriage?
1, Whether parents and children are suitable for marriage: Why parents can have a long marriage all their lives is to find it for their parents. Friends' introduction and relatives' matchmaking can also be attributed to the above two forms respectively. "A twisted melon is not sweet", and only your own feet know whether the shoes are suitable or not. The advantage of children finding their own is that they can find true love.
The reason why children will allow or even hope their parents to choose a spouse for them is mainly because their parents have a wider social network and rich experience makes them more accurate in judging people. Through parents looking for a partner, it also expands the search scope and choice space of children's mate selection, and reduces the cost of children's own search.
Marriage between a man and a woman is not only a match between two people, but also involves the honor and disgrace future of two families or even two families. In the cultural tradition that children support their parents, parents interfere with their children's mate selection mainly for the care of their children in their later years.
If the family remarries to the N power, can children of both parents get married? "There are three kinds of unfilial, none of which is bigger." Parents also want to carry on the family line and have more children, so they want their children to have more children. At the same time, the future mother-in-law doesn't like the disharmony between mother-in-law and daughter-in-law, so she prefers her son to marry an obedient daughter-in-law. For example, a daughter-in-law with a high level of education can work to earn money, but she may be more opinionated and difficult to obey her mother-in-law.
For these reasons, parents will actively participate in their children's marriage. But the daughter-in-law that parents love is not necessarily what their son likes, because the starting point of the two is completely different.
However, parents don't want their children's marriages to be disharmonious or not long. They have a common understanding on this point, but they need to compromise and make concessions in other aspects to reduce the conflict of interests between the two generations. So, although parents are not completely selfish,
2. Are parents and children suitable for marriage? What is the risk of children married between heterozygotes? The basic characteristics of autosomal recessive genetic disease (autosomal recessive genetic disease) are recessive, that is, homozygote, which is manifested as symptoms. Both parents of genetic diseases have basic carriers of pathogens, so they are introduced by close relatives. 1/4 generations, the disease probability is equal, and the basis of hereditary metabolic diseases is recessive genetic diseases. The concepts of enzyme, cis-trans and peptide are different from those of genetic metabolic diseases, and the recessive genetic diseases, such as lysosomal storage disease, glycogen storage disease, lipid storage disease and mucinous storage disease, have different coding bases. Synthase deficiency, gamma globulin deficiency and albinism; Autosomal progressive genetic diseases, such as phenyluria, Wilson's disease and galactosemia, are caused by the recessive pathogenic group. Their characteristics are as follows: ① Parents of patients with homozygous disease group are carriers of disease group (heterozygotes); ② The brothers and sisters of patients are about 1/4, and the pathogenesis of male patients is similar; ③ The family has inherited the parents of several generations of patients. Distant ancestors and collateral relatives have the same disease. The incidence of inbreeding generation increased significantly. Generally speaking, there are 22 bases in each nucleus and 22 bases in each DNA fragment. Each base fragment is dominated by two dominant bases, recessive base and dominant base. The recessive foundation of capital shows recessive characteristics, just like the recessive characteristics of genetic diseases. The shape of genetic disease shows the pathogenic principle of genetic disease. A brief introduction to drawing a genealogy chart: using serial numbers to indicate the relationship between family members. According to the genetic formula, pedigree number 1 and single allele mutation cause four main diseases. According to statistics, diseases caused by the pathogenic basis of species are called dominant genetic diseases or heteromorphism has reached the point that the pathogenic basis of species () can be divided into dominant and recessive diseases, which is different from heterozygosity (Aa). Whether it shows correspondence or heterozygosity (Aa) can show traits related to dominant base A or genetic diseases is called dominant inheritance (1). State (Aa) is characterized by homozygous dominant or completely dominant short fingers, which is an example of completely dominant inheritance. This disease is more common than hand (foot) deformity, which means that (toe) is shortened due to shortening of phalanx or metacarpal bone or lack of phalanx. Family analysis of a case of short finger (toe) (Figure 2) The relationship between male onset and gender. The disease is determined by a certain base, assuming that it is a dominant gene, and the heterozygosity (Aa) indicates that the controlling character of base A shows some clinical symptoms. The characteristics of clinical symptoms are called phenotype or phenotype that does not express base A. In some cases, short finger and short finger patients control multiple phenotypes with the same phenotype. Genetic groups are called basic types or genotypes. Short finger disease basic Aa type. Allele aa is called heterozygote (heterozygote E). People with the same base (aa or Aa) are called homozygotes (homozygotes). The dominant base A of AA is heterozygote, which is the manifestation of short finger disease. The clinical manifestations of two homozygous (AA) heterozygotes are different, so the ratio of patients with short finger disease to fully dominant clinic should be 1: 65438. 2. Both patients with short finger heterozygosity are married, and their 3/4 generations are about 1/4. Figure 4-2: The base type of each patient is heterozygote (aa) () The pathogenic base A is determined from the aa patients of parents, and the three generations of relatives of Aa patients should all be Aa, and they can all complete the family, with a total of 2 1 short finger, 1 (male 55) ② about 1/2 patients; ③ Male pathogenesis is equal (2) Complete dominance: the heterozygote (Aa) phenotype is called complete dominance (
The above is about why parents' lifelong marriage can last for a long time, and why parents' lifelong marriage can be shared for a long time. I read "Are Parents and Children Suitable for Marriage?" I hope this will help everyone!
