辽宁雏蝗不同地理种群染色体研究
Chromosome Analysis in different Populations of Chorthippus liaoningensis Zheng in China
摘要
Abstract
[Objective] The aim was to compare chromosomal karyotypes and C-banding karyotypes of Chorthippus liaoningensis Zheng in three geographic populations.[Method] BSG method was used to carry out the banding treatment.[Result] The three geographic populations had the same chromosomal karyotypes of "1C" type and the same sex-determining mechanism of XO and the same chromosome number 2n(♂) =17 with NF =23.In C-banding,the three geographic populations all had centromeric band with different heterochromatin content.[Conclusion] In view of the chromosome karyotypes and the characteristics of C-banding,the three geographic populations are the same specie.Because the distinct geographical environments,slight differences in C-banding karyotypes are apparent anong the three populations.关键词
