On January 24, 2024, "Brother Ye Becomes Sister" rushed to the top of the hot search.
According to the news released by the Chengdu Giant Panda Breeding Research Base
The giant panda "Kazuha", who used to be regarded as a "male bear", is actually a girl!
And it and the giant panda "Hehua" are actually sisters.
For a while, many netizens who like giant pandas were instantly caught off guard by this news.
Can it be so outrageous?
There are even netizens who ask their souls: Huahua won't be her brother, right?
Indeed, this kind of picture is very scary to think about!
Once upon a time, Kazuye's father "Meilan" was also mistaken for a female bear.
In addition, there are also giant pandas Pu Pu and Fa Fa who have also had a gender reversal.
In this regard, the breeder Grandpa Tan explained: The gender of the panda is a bit complicated. When He Ye was just born, his gender characteristics were biased towards his younger brother, and now as he grows older, his male salient characteristics are not obvious, and then we asked experts to collect biological samples and find out that he is indeed his younger sister.
And about the giant panda because of the gender issue, there is a lot of jokes in the world.
So much so that the Soviet Union and the United Kingdom, once world powers, also held a blind date for two same-sex pandas.
After the founding of the People's Republic of China, in order to promote the friendship and development of the two countries, panda diplomacy appeared on the historical stage.
Generally speaking, panda diplomacy is divided into two phases, the first stage is gifting, and the second stage is lend-lease.
The first pair of pandas presented by the mainland was in 1957, when Marshal of the Soviet Union "Voroshilov" led a delegation to the mainland for a 20-day visit.
Who knew that when everyone visited the Beijing Zoo, Voroshilov's heart instantly fell under the panda's pomegranate skirt.
As a result, the mainland decided to present two pandas, one male and one female, to the Moscow State Zoo, which are Pingping and Moraine.
As a result, after the Soviet Union raised it for half a year, it suddenly reacted to a question to us, obviously it was in estrus, but why didn't the two pandas react, could the two pandas have the same gender?
Don't say it, it's really possible!
Due to the limitations of science and technology at that time, the gender issue of pandas has been bothering many experts in the mainland.
So, in order to let the two pandas of the Soviet Union pass the estrus period smoothly, the mainland took a female giant panda named An An and swapped it with the moraine.
At this point, the outrageous bear life of the moraine officially kicked off.
Two couples of lovers who were torn apart
A year later, the Austrian animal dealer Heini Demer, while visiting the Beijing Zoo, also fell under the pomegranate skirt of the panda.
In order to get it, Heiney Demer exchanged a giant panda with the Beijing Zoo at the cost of 3 giraffes, 2 rhinoceros, and more than a dozen animals such as hippos and zebras.
That's right, this exchange panda is a moraine.
However, I don't know if this group of people really doesn't know the gender of the moraine, or if there is some other reason, anyway, since then, the name of the moraine has suddenly been changed to Ji Ji.
Eventually, Ji Ji traveled all the way across the ocean to London Zoo.
After all, Britain only has pandas, so as soon as it comes to estrus, Ji Ji will begin to "spit fragrant" at the keeper, but is it reasonable!
Originally, Ji Ji had a "baby kiss", now it's okay, thanks to the blessing of this group of people, I was stunned to tear off the red rope that Yue Lao pulled, you say, who is not angry on this place?
So during that time, the keeper who raised Ji Ji was kind of a bunk on the side of the toilet - not far from!
As long as Ji Ji saw him, he didn't say a word, and he went up to be a hammer.
At that moment, Britain realized that it had to find a companion for Ji Ji!
Then Britain didn't even think about it and immediately found the Soviet Union.
And so, a dramatic scene appeared!
There are two countries with different ideologies and deep hatred.
Because of the problem of panda mating, they are like the aunts in the vegetable market, bargaining with each other, for fear that the baby pandas in their zoo will suffer a big loss.
Eventually, after a year and a half of high-level negotiations, the two governments signed a detailed agreement for the marriage.
Outrageous blind date
In 1966, the female panda Ji Ji took a special plane to the Moscow Zoo, who knew that the plane, Ji Ji was dumbfounded.
Due to illness, the male panda Pingping, who was originally "doll kissed" by Ji Jiding, died five years ago.
And the blind date recommended by the two governments for Ji Ji was the female panda An An who exchanged her.
For a while, the rivals in love were very red when they met, and the two bears didn't greet each other, so they started a fight on the spot.
In this way, with the full mediation of the two governments, the in-laws became enemies, and the cave house became a battlefield.
Seeing this, you may ask if you are more handsome than Wu Yanzu!
This is not right, since the male has passed away, why did Britain and the Soviet Union arrange this blind date for An An and Ji Ji, who are also females?
According to the information, An An may not be a female.
However, Cui Zhanping, who served as the first director of the Beijing Zoo, once said in a program that An An is indeed a female.
If the descriptions of both sides are true, then there is only one truth. (The following is the author's guess)
At the beginning, the Soviet Union may have thought that the first two giant pandas Pingping and Ji Ji were both female, so they felt that An An, who was replaced, must be male.
As a result, we thought that the two pandas presented to the Soviet Union were male, so we gave a female.
In this way, both parties may mistakenly think that the other party is what they want.
As for what the basis is, that is, after Pingping's death, mainland experts specially dissected Pingping's body in order to fully understand the body structure of the panda.
The results showed that Ping Ping was not a male, but a female.
(The above is just Ivan's speculation, and those who have an in-depth understanding of this can leave their opinions in the comment area.) ）
Among the many large mammals, the giant panda is the most difficult to distinguish between male and female.
Because rare animal species generally do not use sex chromosome identification methods, they usually identify sex based on secondary sex characteristics or differences in the morphology of exposed male and female reproductive organs, which is very accurate.
But the giant panda is the exception, and the shape of the exposed genitalia of its cubs is very difficult to distinguish.
Unless you are a professional or an experienced researcher, it is difficult to tell the sex of a giant panda.
