YAVRUSU DA D\u0130\u015e\u0130 OLDU<\/strong><\/p>\n

Sardunya’daki Cala Gonone Akvaryumu’nda, son 10 y\u0131l\u0131n\u0131 akvaryumda ba\u015fka bir di\u015fiyle ge\u00e7iren Mustelus cinsi k\u00f6pekbal\u0131\u011f\u0131n\u0131n yavrusu da di\u015fi oldu. Bilim insanlar\u0131 di\u015fi yavruya Maltacada “umut” anlam\u0131na gelen Ispera ismini verdi. Partenogenez diye bilinen bu nadir olay, di\u015filerin kendi yumurtalar\u0131n\u0131 kendi kendine d\u00f6lleyebilmesiyle ortaya \u00e7\u0131k\u0131yor.<\/p>\n

Independent T\u00fcrk\u00e7e’de yer alan haberde, k\u00f6pekbal\u0131klar\u0131, bal\u0131klar ve s\u00fcr\u00fcngenler de dahil olmak \u00fczere 80’den fazla omurgal\u0131 t\u00fcr\u00fcnde partenogenez g\u00f6zlemleniyor. Ancak uzmanlara g\u00f6re bu nadir olay, Mustelus k\u00f6pekbal\u0131\u011f\u0131nda ilk kez g\u00f6r\u00fcld\u00fc.<\/p>\n

ABD\u2019nin Florida eyaletindeki Mote Marine Laboratory & Aquarium isimli deniz ara\u015ft\u0131rma kurumunda g\u00f6rev yapan Demian Chapman, “\u015eimdiye dek birka\u00e7 k\u00f6pekbal\u0131\u011f\u0131 ve vatoz t\u00fcr\u00fcnde bu olay belgelendi” diye konu\u015ftu.<\/p>\n

K\u00f6pekbal\u0131klar\u0131ndaki partenogenez \u00fczerine \u00e7e\u015fitli ara\u015ft\u0131rmalara \u00f6nc\u00fcl\u00fck eden Chapman, s\u00f6zlerini \u015f\u00f6yle s\u00fcrd\u00fcrd\u00fc, ”Ama vah\u015fi do\u011fada bu olay\u0131 tespit etmek zor, bu y\u00fczden sadece tutsak hayvanlardan biliyoruz.”<\/p>\n

Chapman\u2019a g\u00f6re baz\u0131 k\u00f6pekbal\u0131klar\u0131n\u0131n y\u0131llar boyunca partenogenez yoluyla tekrar tekrar do\u011fum yapt\u0131\u011f\u0131 g\u00f6zlemlenmi\u015fti.

PARTENOGENEZ SADECE D\u0130\u015e\u0130LERDE MEYDANA GEL\u0130YOR<\/strong><\/p>\n

K\u00f6pekbal\u0131klar\u0131nda partenogenez sadece di\u015filerde meydana geliyor. Ancak di\u015filer Y kromozomu aktaramad\u0131\u011f\u0131ndan, d\u00fcnyaya gelen yavrular\u0131n da her zaman di\u015fi olmas\u0131 gerekiyor.<\/p>\n

\u00d6te yandan Partenogenez, yavrular\u0131n genetik \u00e7e\u015fitlili\u011fini b\u00fcy\u00fck \u00f6l\u00e7\u00fcde azald\u0131\u011f\u0131ndan, yavrular\u0131n hayatta kalma \u015fans\u0131 da d\u00fc\u015febiliyor. Ancak bilim insanlar\u0131, Ispera bebe\u011fin sa\u011fl\u0131k durumunun iyi oldu\u011funu ve esaret alt\u0131nda nispeten normal bir ya\u015fam s\u00fcrmesini beklediklerini ifade ediyor.<\/p>\n
