If you want to tell whether soybeans are genetically modified or not, it's actually very simple to operate at home.

On how to distinguish genetically modified soybeans, there must be ways, the simplest is to buy genetically modified test strips, you can directly detect whether it is genetically modified products. In addition, it relies on molecular detection instruments to detect the related marker genes by PCR amplification.

But then again, if you want to rely solely on your eyes, I can tell you clearly here that even if you have Sun WuKong's eye, you can't immediately tell whether it is genetically modified or not.

It is rumored in many tutorials that the so-called identification of genetically modified crops by their appearance is very unreliable. First, genetically modified plants do not necessarily change the appearance of crops. For example, transgenic insect-resistant cotton is only enhanced in resistance to insect pests, and you can't see any change in the appearance of cotton. For example, cotton plant height, leaf color, leaf shape, cotton fiber color length and so on will not change. For example, genetically modified high oil content soybean, this kind of soybean only has an increase in oil content, but there is no other change, and its appearance is basically the same as that of ordinary soybean. In this way, how can soybeans be identified by their appearance?

In addition, I would like to explain to you the source and use of genetically modified soybeans in China. According to the relevant regulations of our country, genetically modified soybeans are used to extract oil and soybean meal as feed, but from the source, domestic commercial cultivation is not approved, so genetically modified soybeans are imported from abroad. Not only the United States has genetically modified soybeans, imported Brazilian soybeans and Argentine soybeans are also genetically modified soybeans. It must be clear from the above introduction that we have no access to genetically modified soybeans in the supermarket. Therefore, there will be no problem of consumers buying GMOs.

With regard to the issue of soybean black belly button, it is clear here that this is only a character of soybean, and it has nothing to do with whether it is genetically modified or not. Anyone who has studied Mendelian inheritance should understand the relative genetic traits, such as the yellow and green, round and wrinkled types of soybeans.

Therefore, if you want to judge whether it is genetically modified or not, it is necessary to choose the right method. Although there are no genetically modified soybeans on the market, if you are not assured, you can buy a genetically modified test strip to test it yourself.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
