Huahua, the “top leader” in the panda world, and Heye, the “younger brother”, have always attracted everyone’s attention.
As Heye grows older, its male distinctive features become less obvious. Recently, breeders invited experts to collect biological samples from Heye, and found that Heye is actually a "sister".
On January 24, in the latest video released on the WeChat public account of the Chengdu Giant Panda Breeding Research Base, the breeder "Grandpa Tan" revealed that after expert identification, the giant pandas "He Ye" are female, and "He Hua" and "He Ye" are female. sisters.
In this regard, Grandpa Tan explained: The gender of pandas is a bit complicated. When He Ye was first born, his gender characteristics were biased towards his younger brother. Now as he grows older, his distinctive male characteristics are not obvious. Then we asked experts to collect biological samples and found out that he is indeed the younger sister. As soon as the news about
came out, many netizens who were concerned about He Ye were confused. While
was surprised, he also began to work hard for the "sisters".
Some netizens asked from the bottom of their hearts: Could Huahua be the elder brother?
In fact, He Ye's father "Meilan" was once mistaken for a female, 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 really 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.
