dc.description.abstract本文对驯养于实验室自然海水中的蒙古裸腹溞(MOInA MOngOlICAdAdAy)染色体进行了分析、研究。结果表明:蒙古裸腹溞染色体数目为n=12, 2n=24。其中10条为中部着丝点染色体,2条为亚中部着丝点染色体,12条为端部着丝点染色体,总臂数nf=36。其核型公式为2n=10M+2SM+12T。本文还与溞属(dAPHnIA)6个种类的染色体形态进行了比较,并对蒙古裸腹溞孤雌生殖与两性生殖及性转化的问题开展了讨论。
dc.description.abstractAn karyologic analytical study is carried on the chromosome of Moina mongolica Daday, by means of hot-dropping method, from the population that have been cultured in natural sea water under laboratory conditions.Observed results show that the chromosome number of this species is n=12, 2n=24, and that 10 of these chromosome group metacentric, 2 sub metacentric and 12 telocentric.The karyotypc formula of 2N=10M+2SM+12T is suggest ed.Chromosome morphology among 6 species of Daphnia is compared(Collcerning with aga- mocytogony, sexual reproduction and sexual differentiation of Moina mongoloca are discussed in the present paper.
