The distribution of a Y-chromo some specific polymorphic loucs, DYS19, in 535 males o f ten ethnic groups in China w as studied by using PCR method follow ed by PAGE and silver staining. The ten ethnic groups a re Han in Shanxi Province, Han in Guangdong Province, Hui in Ningxia Hui Autonomous Region, M an in Liaoning Province, Uygur in Xinjiang Uygur Autonomous Region, Yi in Sichuan Province, Tibetan in Tibet Autonomous Region, Zhuang in Guangxi Zhuang Autonomous Region, Yao in Guang xi Zhuang Autonomous Region, Tujia in Hunan Province. The result show s that allele C ( 194bp) , frequency o f which rang es from 0. 25 to 0. 61, is predominant in Chinese populations; alleles B ( 190bp) and D ( 198bp) take the second place with the frequency ranging from 0. 08 to 0. 36 and 0. 06 to 0. 42, respectively; while alleles A ( 186bp ) and E ( 202bp) take the last place with the frequency ranging from 0 to 0. 07 and 0 to 0. 38, respectively. An individual carrying the allele F ( 206bp) was identified in Zhuang. The pairwise comparison with χ2 test reveals that there exists difference ( P < 0. 05) o r significant difference ( P < 0. 01) in DYS19 phenotype distribution between Yao、 Tibetan and most other Chinese populations. The allele frequency of DYS19 in Chinese ethnic groups has no t been reported so far.

The genentic polymorphism of Gc and PGM 1 w as studied with thin layer polyacryamide gel isoelectric focusing (PAG-IEF) and that of AcP1 , 6-PGD, ADA, and AK1 with starch gel electrophoresis combined with specific staining in She ethnic group in Fujian Province. Their gene frequencies obtained are: Gc* 1F 0. 4722, Gc* 1S 0. 2421, Gc* 2 0. 2738; PGM 1* 1A 0. 5357, PGM 1* 1B 0. 1627, PGM1* 2A 0. 1587, PGM 1* 2B 0. 1429; AcP1* A 0. 1825, AcP1* B 0. 8175; 6-PGD* A 0. 9683, 6-PGD* B 0. 0278; ADA* 1 0. 9881, ADA* 2 0. 0119; and AK1* 1 1. 0000. There is monomorphism in locus of AK1 in She population. Three cases with rare variant allele ( Gc* 1A2) w ere found in Gc with a frequency of 0. 0119, and one case with 6-PGD* R in 6-PGD.

The 283 teeth of 16 human skulls unearthed at neolithic site o f Zengpiyan cave in Gualin of China w ere observed. The frequency of dental caries is 93.75% . The DMFT is 6. 07. This frequency is much higher than that of other Stone Age population and that of modern population living in the same area.

A survey of somatology and anthropometry on 251 persons of Tu nationality ( 131 males and 120 females, ranging from 20 to 55 y ears in ag e) living in Qinghai province was made in July amd August, 1995. The results are summarized briefly as follows.
Opening height of eye is medium in majority of males. The opening eye is high and wide in more than half of the females. The frequency of appeanace of epicanthus is higher than 50% in males while it is 40. 8% in females.
Eyefold of the upper eyelid was seen in more than 94% in both sex. Nasal index belong s to mesorrhine. Length-breadth index of head belong s mesocephaly. Morphological facial index belong s to hyperleptoprosopy , leptoprosopy and mesoprosopy in males.
The average statures a re 1634mm in males and 1543mm in females. From the cluster analysis covering 15 nationalities in China it can be seen that Tu nationality is closer to Dongxiang , Baoan and Qiang nationalities.

This paper reported the singing ecology and behavior of concolor gibbon in Yunnan, P. R. China based on the field studies o f a yearly monitered group GS in 1995 and some other groups such as GA, GC and GG monitered and studied from Ma r. 1990 to Jan. 1992. Mated gibbons usually sing duets in morning , and mo st o f them occurs before 0930 hr. The start time of duet, however, shows that there are two peaks ( around 0730 hr occurred from July to Oct. and 0830 hr from Nov. to June) annually , and also show s no consensus with the dawn time. Generally, concolor gibbons sing once every two days, the average daily singing occurrence of GS is 47. 5% and that o f GA is 54. 3% , and the occurrence changes with seasons, e. g. , it drops to 10% in GS in May and rises up to 80% in GA in Sept. The duration show s no significant difference between groups ( P> 0. 10) , the media n length of duets is about 12 min. , but there is a monthly difference in group. An exception is GG, which sing s an average of 19. 6 min. ( SD= 4. 2, n= 16) , much longer than all other groups. And this paper does no t verify the result that singing of a group would trigger singing of other groups.
