Nucleic acid hybridization (non-specific hybridization)

Crossing sheep and pigs? This new species has become a national treasure of Hungary and won a gold medal at the Budapest exhibition.

Original 2021-09-03 17:00 Why is Gao Daqiang here, but sheep and pigs from different “worlds” are secretly in love? With what advantages can a new species become a national treasure of Hungary? What’s the big secret behind winning the Dallas Gold Award? Hello everyone, I am Qiangzi, follow me into today’s story.

A pig in sheep’s clothing was found.

For many of us, sheep and pigs are not uncommon in life. These two animals are kept in most homes or factories. Generally speaking, farmers raise pigs mostly for the purpose of selling pork. But the meat quality of sheep is not delicious. It is more about collecting wool, wool products used in daily life, and so on. In our impression, these two animals have nothing in common in their living habits, and it is even more impossible to find any special connection between them, but it is strange that

There is an animal with the curly coat of a sheep and the body of a pig. This makes us soberly aware that sheep and pigs who cannot fight seem to coexist. This is a refreshing sheep and pig. Pigs are also known as Lincolnshire Curly pigs. You can’t imagine that they are covered with fluffy curly hair, which is dense but soft. Its hair also has a magical effect, that is, it will not break after being soaked underwater for a long time, so it is used by people to tie flies as bait.

In addition, sheep pigs are about the same size as ordinary pigs. Sheep pigs grow slowly and must be raised naturally, because their meat contains more trace elements and fatty acids than ordinary pork, so that sheep and pigs were once sold for a high price of 1,000 US dollars, becoming a veritable treasure among pigs. Because of the appearance of sheep and pigs, its origin has been questioned again. What happened? Originally, sheep pigs originated in Hungary and Australia. At that time, as soon as this rare species was discovered, it attracted people’s attention and gained a lot of social attention.

People’s curiosity makes sheep and pigs slaughtered again and again. In addition, due to the small base and slow breeding speed, the number of sheep and pigs in the two countries has plummeted. At the same time, changes in the climate and environment of the two countries have also brought great challenges to this species, and the “pig in sheep’s clothing” has since disappeared from people’s vision. This makes people wonder why the sheep and pigs, which were declared extinct 37 years ago, miraculously resurrected, and what is the meaning behind the unprovoked resurrection? Pay attention to Qiangzi and take you to explore the secret of resurrection.

“Hybrid” sheep and pigs

When it comes to sheep and pigs, you may not be familiar with them. small case. The word mule should be familiar to everyone, especially when we see pictures of mules, we will be surprised to find that this guy is somewhat similar to a horse on the grassland. Is it still a bit like an enlarged version of a donkey? Yes, I want to see that everyone here understands. In fact, a mule is a hybrid of a horse and a donkey.Turn in the new creatures you get. So what is hybridization?

Could hybridization produce creatures we’ve never seen before? In fact, hybridization is the base pairing of two single-stranded DNA or RNA. Simply put, it is an individual method, allowing individuals of different genotypes to mate with each other and recombining some parental genes. It is a cross between a mule and a donkey. At the same time, the mule has inherited the speed of the horse and the stamina of the donkey, which not only highlights the advantages of the two, but also saves labor costs.

I don’t know if you have observed it carefully. During the Northern Song Dynasty, the “Golden Rooster and Lotus Picture” created by Emperor Huizong of Song Dynasty is an imaginary cross picture in Chinese history. The chicken body is mainly composed of red and white. According to research, there was no golden pheasant of this color at that time, so it should be painted by white-bellied golden pheasant and red-bellied golden pheasant, and any color and the author’s imagination should be taken. However, with the change of geography, geographical researchers found that in Southwest China, the habitats of the two types of golden rooster overlapped each other.

So the golden pheasant in the picture is very common today. There’s also the popular pink fairy bottlenose dolphin, which has been found to interbreed with a variety of dolphins, resulting in more than 13 species of creatures. Like rhino dolphins, cetaceans are hybrids of dolphins and killer whales. With little common intersection between them, there are currently only two cetaceans living in their common habitat, and their offspring share some of the salient features of the previous generation.

For example, in terms of skin color, the skin color of the offspring is between the two, and other organs also overlap to a certain extent. From the above cases, it is not difficult for us to deduce whether sheep and pigs are also hybrid animals. If it is obtained by crossbreeding, what animal will it be crossbreeded with? Note that Hadron will show you why sheep and pigs reappeared.

The reason for the disappearance and reappearance of pigs

As with most crosses, sheep and pigs both meet the requirements of crosses, but we may have overlooked one point. Is there any technology besides hybridization that can make sheep and pigs reappear? With the continuous development of science and technology, it seems that it is no longer difficult for human beings to produce a new animal. Scientists have devoted themselves to research and applied these technologies where they are most needed, including the familiar cloning technology. Through this technology, people began to use it to save endangered animals. To protect plants and animals that reproduce slowly,

This technique is also used to expand their numbers. According to reports, scientists have used cloning technology to save many animals. Among them, Dolly the sheep is a typical one, but the most successful one is the black-footed ferret, an endangered mammal in North America. But it is worth pondering that the ferrets at that time were already in an endangered period. Experimenting with the last remaining organisms may be the last game. At this time, some audience friends may say, why not use hybrid technology? Answering this question requires us to know more about the conditions of hybridization, which is that the two sides of the hybrid must be of different species, just like horses and donkeys are different species. In fact, cloning is just a copy. to copy a completeFor identical individuals, we must find a complete set of genetic information. As you can imagine, 37 years ago, no one realized the need to protect genetics, because at that time no one thought that sheep and pigs would disappear, so we basically ruled out the possibility of sheep and pigs appearing through cloning technology. Going back to the hybridization technology we mentioned above,

Sheep and pigs have curly hair and piglet shape at the same time, which seems to be a better proof. Sheep and pigs may really have come from interbreeding. If this is the case, then we can give a plausible explanation for the extinction of sheep and pigs. Before that, Qiangzi would like to ask you a little question. Have you ever seen a mule breed? Do you know why there are so few whales and dolphins? The reason for its original premium source 100% is due to hybridization. The result of interbreeding is reproductive isolation. Generally speaking, the offspring produced by crosses are highly sterile.

They cannot have offspring. 37 years ago, sheep and pigs were over-eaten but not protected to help them survive and reproduce. So their state is to eat one, one less, only decrease but not increase, resulting in a sharp decline in the number of sheep and pigs. Coupled with the influence of other external factors, sheep and pigs gradually disappeared from people’s field of vision. Thirty-seven years after the sheep and pigs disappeared, in order to make the sheep and pigs reappear, the Englishman York started a long journey of raising pigs. He found the human Grica pig with pure blood.

Mate this pig with a curly-haired pig to get the sheep pig we see today. We have already explained that at that time the close relatives of curly-haired pigs and sheep pigs, Manglika pigs, lived far away, were reproductively isolated from each other, belonged to two species, and were eligible for hybridization; at the same time, the number of hybrid offspring was very small , it is difficult to maintain the survival of such organisms, which is also in line with the law of high sterility of hybrid species.

Hearing this, everyone should understand that the reason for the appearance of sheep and pigs came later. So, since hybridization can produce new species, and there are thousands of new species, why do sheep and pigs become the national treasures of Hungary and win gold medals in the Budapest exhibition? Pay attention to Qiangzi and take you to unlock why sheep and pigs are honored.

If a thing is rare, its price is very high – the rarer the better

Because of people’s love, sheep and pigs were popular at the time Hungarian pigs were sold at a high price of 1,000 US dollars, more than five times more expensive than ordinary pigs in the same period. In addition to people’s enthusiasm for driving up prices, the pig hair of sheep and pigs is also collected like wool. One animal has two biological values, which not only meets people’s needs for wool, but also ensures people’s food needs. Another reason why sheep and pigs take the top spot is that rare things are more expensive.

Nowadays, the collector’s edition and exclusive edition activities launched by various merchants are sought after by people because of their rarity, which just confirms that “things are rare and precious, and things are precious”. Rare is more expensive”. Pigs live in two corners of the world, Hungary and Australia, they are famous for having the few rare animals in the worldIt attracted the attention of the world, and the pig that brought honor to people also got what it deserved, and successfully won the Budapest Gold Medal.

That’s why some people regard sheep and pigs as the national treasures of Hungary and won the Budapest Gold Medal. Friends, do you think the friendship between sheep and pigs is the result of today’s biotechnology, or the result of natural hybridization? Please leave a message to discuss with us.
