Baiklah Pada Kesempatan Kali Ini Catatan_Kemal Akan Memberikan Sedikit Info Yang Sangat Aneh !
Yuk Kita Simak Bersama ^_^

Pasangan Inggris menyaksikan hewan peliharaannya, Gertie si ayam betina, perlahan berubah menjadi ayam jago. Ayam ternyata bisa mengalami perubahan jenis kelamin secara alami. Gertie milik Jim dan Jeanette Howarrd di Huntington, Inggris, ini awalnya berhenti bertelur serta bertingkah layaknya ayam jago. Selama beberapa pekan, Gertie bertambah berat badan dan pial di bawah dagu muncul, fitur ini biasa terdapat pada ayam jago. Selain itu, jengger merah pun muncul di atas kepalanya. "Saya tahu hal ini terdengar konyol. Namun, hal ini benar terjadi," kata Jim Howard pada cambridge-news.co.uk.
Menurut laporan Institute of Food and Agriculture Sciences University Florida, perubahan jenis kelamin bisa terjadi, meski jarang. "Hingga kini belum pernah ada laporan adanya perubahan jenis kelamin spontan dari jantan ke betina." Nampaknya, mekanisme fenomena biologis ini hanya bekerja satu arah. Umumnya, ayam betina hanya memiliki satu ovarium di sisi kiri. Dua organ jenis kelamin muncul selama masa embrio semua burung. Ketika gen betina muncul, organ ovarium muncul. Di sisi kanan, terdapat gonad yang merupakan testis dan ovarium yang biasanya tidak aktif. Kondisi medis tertentu, seperti tumor atau penyakit, bisa menyebabkan ovarium menghilang. Menurut profesor Penn State University Mike Hulet, organ seks di sisi kanan pun mulai tumbuh. "Jika diaktifkan, organ itu akan mulai mengeluarkan androgen," ungkapnya. Androgen merupakan karakteristik pejantan yang biasa dikeluarkan testis. "Produksi androgen memicu perubahan perilaku dan membuatnya bertingkah layaknya ayam jago," katanya. Transisi ini hanya membuat ayam tampak seperti ayam jago, namun secara genetis tetap ayam betina. Sementara ayam ini tak bisa bertelur dan juga tak bisa membuahi.

British couple watched their pets, Gertie the hen, slowly turning into a rooster. Chickens can apparently change sex naturally. Gertie owned by Jim and Jeanette Howarrd in Huntington, England, was initially stopped laying eggs and behave like a rooster. For several weeks, Gertie gained weight and wattles under the chin appears, this feature is commonly found in rooster. In addition, red cockscomb appeared above his head. "I know it sounds ridiculous. However, this is really happening," said Jim Howard at cambridge-news.co.uk.
According to the Institute of Food and Agriculture Sciences University Florida, sex change can occur, although rarely. "Until now there has never been any reports of spontaneous sex change from male to female." Apparently, the mechanism of this biological phenomenon only works one way. Generally, hens only have one ovary on the left side. Two sex organs arise during all avian embryo. When the females emerge genes, organs ovary appears. On the right side, the gonads are testes and ovaries are normally inactive. Certain medical conditions, such as tumors or disease, can cause ovarian disappear. According to Penn State University professor Mike Hulet, sex organs on the right side began to grow. "When activated, it will start issuing organ androgen," he said. Androgens are male characteristics are usually issued testis. "The production of androgens trigger behavioral changes and make it behave like a rooster," he said. This transition only makes the chicken look like a rooster, but remained genetically hen. While the chickens can not lay eggs and also can not fertilize.
