Shaoyang men donated blood 7 1 time after learning that they were panda blood. Is this behavior commendable? A man in Shaoyang donated blood 7 1 time after learning that he was panda blood. This behavior of men is particularly commendable. Knowing that blood can save lives, especially this kind of rare blood group, can save lives in times of crisis, which is a great blessing for the people. He did not hesitate to ask for something in return, donating blood 7 1 time. I still have the following views on the man's behavior:

1. What is rare blood group?

Rare blood group is a rare or extremely rare blood type, just as panda blood refers to RH negative blood. With the development of blood group research, scientists established rare blood group and rare blood group systems respectively. The common blood types on weekdays are A, B, O and AB.

Second, how is panda blood formed?

Panda blood refers to RH negative blood. Most people in China belong to RH positive blood. Ethnic minorities have a certain proportion of erh negative blood, so it is called panda blood. Most of the formation of panda blood is related to genetic factors, and very few are related to gene mutation. When one parent carries RH gene, parents will pass it on to the next generation, which will lead to the emergence of RH-negative blood gene in the next generation.

Third, Shaoyang men mobilize people around them to do good deeds together.

After discovering that he was panda blood, Shaoyang men actively mobilized their families to test their blood types and encouraged people around them to donate blood. He and local volunteers vigorously promoted the benefits of blood donation. He is an ordinary farmer, donating blood for 7 1 time, 15 years. It is understood that this person started from the village before dawn, and it was already dark when he got home, after passing through the media. This man's behavior is worth learning.
