THE KARYOTYPE OF MARM0TA HIMALAYANA

Abstract

Abstract: Marmota himalayana is one of the wild mammals，and widely spread on alpine meadow on Qinghai-Tibetan plateau.A1though there were some reports about its geographicdistribution，indoor raising，reproduction etc.it hasn't been reported to date about its chrom- osome study．By using the mothod of peripheral lymphocyte
culture the karyotype of the animal has been studied．The results are as follows
1．The diploid chromosome number of karyotype:2n= 38;
2．Autosomes: 24 metacentrics and submetacentrics,12 teloeentrics and subtelocentics;
3.Sex chromosomes,;X submetacentrie; Y telocentric．

Key words: Marmota himalayana, karyotype, chromosome

摘要： 作者采用外周血淋巴细胞培养方法，研究喜马拉雅旱獭的核型。染色体数目，2n=38。常染色体中有24个中着丝粒和亚中着丝粒染色体；12个端或亚端着丝粒染色体。x为亚中着丝粒染色体，Y为端着丝粒染色体。
