On January 24th, a sudden news hit the top of the trending list #和叶 brother turned into sister #
According to news from the Chengdu Giant Panda Breeding Research Base on the 24th, the giant panda Heye, who was previously regarded as a "male bear", is actually a girl. Breeder "Grandpa Tan" revealed that when the giant panda "He Ye" was born, his gender was biased towards the "younger brother", so in the past few years, he has been mistaken for a male giant panda.
However, as it grew up, researchers found that its male characteristics were not very obvious, so they invited experts to identify her, and after testing biological samples, she was determined to be the "sister".
In fact, He Ye's father "Meilan" was once mistaken for a female bear, and the giant pandas Pu Pu and Fa Fa also experienced gender reversal. Why do giant pandas have gender problems? Among many large mammals, giant pandas are the most difficult to distinguish between male and female. Because rare animal species generally do not use sex chromosome identification methods, the sex is usually identified based on secondary sexual characteristics or the difference in the shape of exposed male and female reproductive organs. This method is very accurate. The giant panda is an exception. The shape of the exposed genitalia of its cubs is difficult to distinguish. If you are not a proficient person or an experienced scientific researcher, it is indeed difficult to distinguish between male and female. As soon as this news came out, it immediately triggered a heated discussion among netizens.
Netizens were surprised, but also began to live for the "sisters".
