几种鼢鼠染色体组型和血清LDH同工酶电泳的比较研究

本文报道了中华鼢鼠指名亚种、甘肃亚种、四川亚种、罗氏鼢鼠的染色体组型和LDH同工酶电泳。发现中华鼢鼠3个亚种染色体数2n=60,罗氏鼢鼠2n=58;中华鼢鼠指名亚种和甘肃亚种LDH同工酶酶谱带数为3条,而中华鼢鼠四川亚种和罗氏鼢鼠为2条。同时,对分类学上争论的问题进行了讨论。

A COMPARATIVE STUDY OF THE KARYOTYPES AND LDH ISOENZYMES FROM SOME ZOKORS OF THE SUBGENUS EOSPALAX,GENUS MYOSPALAX

This paper reports the karyotypes and LDH isoenzyme of M. f. fontanieri, M.f. cansus, M.f. baileyi, and M. rothschildi. 1. Comparative study of karyotype:The chromosome numbers of the three subspecies of M. fontanieri are 2n=60, but of M. rothschildi is 2n=58, There is a couple of the smallest dot chromosomes in all of these types, and X chromosome appeares to be the large metacentric chromosome, Y chromosome to be the small submetacentric chromosome. There are differences not only in the numbers of chromosome but also in types and sizes on the basis of different species and subspecies.
