在实验室条件下，培养了一个采自青海尕海湖的孤雌生殖卤虫(Artemia parthenogenetica of Gahai)的克隆。该克隆包括3578个雌体和103个罕见雄体，在这些罕见雄体中发现二例雌雄嵌合体。其外部形态均表现为雄性，即具有正常的执握肢和外交接器，但在其体左侧出现了正常形态特征的卵细胞，表明在这两个外表为雄性的卤虫中有卵巢存在，为雌雄嵌合体。  相似文献   

A bilaterally partitioned colouration of a narrow-clawed crayfish Pontastacus leptodactylus (Eschscholtz, 1823) in the Lake Eğirdir (Central Anatolian,Turkey)     

《Limnologica》2021

Our observation of a bilaterally partitioned colour phenotype of crayfish Pontastacus leptodactylus from Lake Eğirdir in Turkey was the first for this species. The specimen exhibited unusual body coloration with its right half colored light pinkish-orange and left half was natural in colour. Although the cause of the color pattern in the sampled P. leptodactylus could not be fully determined, the hypotheses regarding previous similar phenomena in crustaceans are related to mutation during embryogenesis and bicoloured gynandromorphy.  相似文献
