If grandpa and grandson do paternity test, what will they find out?

Idle eggs have nothing to do, and personal appraisal is the last resort. How many people in the world have done personal identification? You don't need to say that your grandfather and grandson are personally appraised. After all, there are setter's parents.

It can be used as scientific research, and its legal and social significance is almost zero.

The importance of paternity test is the result of father's sperm conception. People are usually called generations, and the standard language is called "heredity" or genetics. For example, AB is a couple. A is the husband, B is the wife, and a son is born. After paternity test, blood cells leave the father factor. If the child is conceived with another man, the result will be different. The effect is very accurate. Any woman who has given birth to a husband can be identified in a short time. Advise those women who forget ethics for the sake of bad addiction to stop. Back to the topic, what is the purpose of grandpa's paternity test for his grandson? There is a joke about whether grandpa and his daughter-in-law have an affair. If so, its main gene must be "leaf" species. If not, the grandson's main gene is his father, but whether this "father" is "positive" or "wild" depends on the "paternity test results"!

Don't you know this? Dare not talk nonsense! [Laugh] [Laugh] [Laugh]

At least more than 80% are the same.

Regardless of this proof that the two men are father and son, what does it mean to find out the result?

You mean this grandson and his nominal father are half-brothers? Father-son relationship with his nominal grandfather? Is it the mother of the child or his sister-in-law? It's a little messy, let me stroke it!

The paternity test between grandpa and grandson is called grandpa's paternity test. The same paternal line makes Y chromosome, and the same maternal line makes mitochondrial DNA. The relationship between other grandfathers cannot be directly identified, and other schemes need to be sought.

General paternity testing is between father and son, or between mother and child. The difficulty coefficient of paternity test between grandparents and grandchildren is relatively large. Generally, through the comparison of gene sequences, we can find out how many identical gene points there are, and then meet a certain number of identical gene points to determine the genetic relationship.
