A s maternal grandmother s father and B s grandfather are brothers, so A and B can get married

You can get married

Medically more than three generations.

I don't know the law, but the law says that close relatives can't get married, and more than three generations should not be considered close relatives.

But you need to think about your child's problems.

There is nothing wrong with getting married, but your offspring should not be very good in medicine.

That's a big deal.

If two people are in love and don't want children, get married.

If the two of them can bear all the bad things of the child, it's no problem.

In fact, there is a certain probability that the child's affairs are not comprehensive.

I wish you all a healthy baby

Legally yes. Ethically inappropriate, inferior. It will cause confusion of the names of relatives and confusion of generations.

There is no grass at the end of the world, and it is better not to be together. Regardless of whether the offspring will have obvious intellectual problems or deformities, although there is only a certain chance, the impact is far-reaching and long-lasting, and children who are closely related by blood are at least not smart.

If there are three generations of people in the two families, and the three generations are not related (blood) related, it is fine. Otherwise, most of the children born are mentally retarded, brain-damaged, and have a variety of terminal diseases.

Yes, they are more related than the legal F3.

Legally, you can't do it, you have to be more than three generations old, but as long as you don't want children, you can't.

You can get marriedIt's better not to have children, it's better not to, in case there is something wrong with the problem, it's very troublesome, I advise not to have children.

Yes, it's just a bit of a bad junior.

Answer]: A The calculation method of the collateral basic blood relatives is as follows: first find out the direct blood relatives of the same origin, and then count them from the body up to the direct blood relatives according to the calculation method of the direct blood relatives, and write down the number of generations; Then count the number of generations from the collateral blood relatives to be counted to the same direct blood relatives.

If the number of generations on both sides is the same, then the number of generations on one side of the air front is used to determine the algebra; If the number of generations on both sides is different, the side with the larger number of generations is used to determine the algebra. According to this method, A and B belong to the fourth generation of collateral blood relatives.

According to the provisions of China's Marriage Law, marriage is prohibited between immediate family members, collateral relatives within three generations, and aunts and cousins of the same nationality. In this case, if Zhang's maternal grandfather and Li's maternal grandmother are brothers and sisters, their relationship is collateral relatives, so Zhang and Li cannot get married. Such marriages are considered consanguineous marriages, i.e. they are prohibited by law.

It is worth noting that China's marriage law explicitly prohibits consanguineous marriages, mainly for the sake of protecting the health of the next generation. If consanguineous marriages become the norm, it may lead to an increased risk of genetic diseases as the number of consanguineous unions increases, which can adversely affect the health of the next generation.

The answer to this question is b. This is an analytical reasoning question, and it takes some time to find out the specific gender and age of several people, but if you only exclude the options according to the stem conditions, you can quickly get an answer. From "C is a girl, and the shaft stove has an older sister and a younger sister", it can be seen that 3 out of 6 girls sell slippery, and there are also 3 boys, excluding item C; From "A is a boy, there are 3 sisters who play sisters", it can be seen that the 3 girls are all ranked in front of A, excluding A and D.

Therefore, the answer is B.

Summary. A and B are in love and are about to get married, and when the parents of both parties meet, they discover the fact that A's mother is with B. Answer: No, it is a marriage of close relatives within three generations.

A and B are in love and are about to get married, and when they meet with their parents, they discover the fact that A's mother and B's grandmother are siblings, and A's father is with B.

A and B are in love and are about to get married, and when the parents of both parties see the envy of each other, they discover the fact that A's mother and brother are not in love with B. Answer: No, it is a marriage of close relatives within three generations.

Fellow, I really didn't understand, I can be more specific.

If they intermarry, they are called consanguineous marriages. They both have too many similar genes for their offspring to mutate from them, and the harmful genes are passed on to their offspring. Legal basis:

Article 1,000 and 48 of the Civil Code: Marriage is prohibited for direct blood relatives or collateral blood relatives within three generations.

Answer]: B This question belongs to the comprehensive understanding and application of concepts and laws, and the knowledge points of the assessment are the calculation methods of collateral blood relatives in China's marriage law. China's "Marriage Law" calculates the unit of kinship and distance is "generation".

For example, article 7 of the Marriage Law stipulates that marriage is prohibited for collateral blood relatives within three generations. Generation refers to generations, with one generation as a generation. Collateral consanguinity is calculated as:

First of all, find out the direct blood relatives of the same origin, count from the body up to the direct blood relatives according to the calculation method of the direct blood relatives, and write down the number of generations; Then count down from the same direct blood relatives to the collateral blood relatives to be counted, and write down the number of generations. If the number of generations on both sides is the same, the algebra on one side is used to determine the algebra. If the number of generations on both sides is different, the side with the larger number of generations is used to determine the algebra.

Therefore, option B in this question is correct, and the other options are excluded.

Commentary] (1) The legal provisions of the Marriage Law prohibiting marriage between collateral blood relatives within three generations should be mastered;

2) It should be able to accurately calculate the lead and lead algebra of blood relatives in China according to the calculation method of collateral blood relatives in China's "Marriage Law".
