1月24日上昼，成王人大熊猫繁育参议基地微信公众号发布一条视频，视频中谭爷爷对着“花花”“和叶”喊“两姐妹”。这让网友恐惧不已：畴前的和叶弟弟果然酿成了妹妹？

On the morning of January 24th, the Chengdu Panda Breeding Research Base's WeChat official account released a video. In the video, Grandpa Tan addresses "Hua Hua" and "He Ye" as "two sisters". This has left netizens in shock: the former brother, He Ye, has turned into a sister?

谭爷爷诠释谈，“和叶”刚出身时，性别特征偏向于弟弟，包括排尿高、个子大、秉性直率等。但跟着“和叶”安定长大，雄性特征就不昭彰了，于是请了民众麇集生物样本，查出来如实是“妹妹”。

Grandpa Tan explains that when He Ye was just born, the characteristics leaned towards being a brother, including higher urination, larger size, and lively personality. However, as He Ye grew, the masculine features became less evident. Experts were consulted, and through biological sample analysis, it was confirmed that He Ye is indeed a female.

为什么会出现大熊猫性别乌龙？在稠密大型哺乳动物中，大熊猫是最难分辨牝牡的。荒芜兽种一般不接收性染色体鉴识法，相通王人所以第二性征或外露的牝牡生殖器官花式的相反来识别性别，这种身手迥殊准确。偏巧大熊猫是个例外，它的幼兽外露的两性生殖器的花式的确难以分辨。

Why does the giant panda's gender become a puzzle? Among many large mammals, giant pandas are the most challenging to distinguish between male and female. Rare species usually don't use chromosomal sex determination; instead, they rely on secondary sexual characteristics or external differences in reproductive organ morphology to identify gender, which is highly accurate. However, giant pandas are an exception. The morphology of their external reproductive organs in cubs is difficult to distinguish.

因此，唯有成年熊猫才能从外生殖器分离性别，但还得仔细不雅察才行，这是与其他动物不同的。

Therefore, only adult pandas can be differentiated by external genitalia, requiring careful observation, making them different from other animals.
