| 中文摘要 | 本文对我国云南南部的白须长臂猿（Ｈ．ｌｅｕｃｏｇｅｎｙｓ）染色体的Ｇ带、Ｃ带、晚复制带及Ａｇ－ＮＯＲｓ进行了较为详细的研究。它的２ｎ＝５２，核型公式为４４（Ｍ或ＳＭ）＋６（Ａ），ＸＹ（Ｍ，Ａ）。Ｃ带表明一些染色体着丝点Ｃ带弱化；有的染色体出现插入的和端位的Ｃ带；Ｘ染色体两臂有端位Ｃ带，Ｙ染色体是Ｃ带阳性和晚复制的。Ａｇ－ＮＯＲｓ的数目，雌体有４个，雄体有５个，Ｙ染色体上具ＮＯＲ。本文对白颊长臂猿与其它长臂猿间的亲缘关系、核型进化的可能途径进行了讨论。 |
| 英文摘要 | White-cheeked gibbon (H.leucogenys) is distributed in the south of Yunnan,China.The chromosomes of a female and a male were studied by several banding techniques (G-,C- and Ag-staining),and a techniqe for simultaneous exhibiting chromosome replication patterns and late replicating Y chromosome.The diploid chromosome number is 52.There are 22 pairs of metacentrics or submetacentrics (Nos.1-22 );3 pairs of acrocentrics(Nos.23-25),and chromosomes Nos.23-24 with a secondary constriction near the centromere on the short arm.The X chromosome is a large metacentric,and the Y,the smallest acrocentric.Its karyotype formula is 44(M or SM)+6(A),XY(M,A).The centrimeric distribution of heterochromatin has been demonstrated in some chromosomes.In addion,there are 3 kinds of heterochromatin on the chromosomes:(1) absent of centromeric heterochromatin,(2) interstitial heterochromatin,(3) terminal heterochromatin.Interstitial heterochromatin has been observed on the biarm of X chromosome.Y chromosome is completely C-band positive.Silver staining revealed 5 chromosomes with NORs in the male specimen.4 Ag-NORs of them are located on the secondary constriction of chromosomes 23 and 24 respectively,and one of them is located on the Y chromosome which has been confirmed by Fluorescence in situ hybridization (FISH) in the same cell.There are 4 chromosomes with Ag-NORs in the female specimen,and they are also located on the secondary constriction of chromosomes 23 and 24.Moreover,the association of Ag-NORs have been observed.Base on the above results,the relationship in gibbons and the way of chromosome evolution in the genus Hylobates have been discussed. |
