To detect QTL for the body fat-related carcass traits in beef cattle, the single strand conformation polymorphism assay was used for investigating the K232A substitution in DGAT1. Animals from 4 beef cattle populations (32 Luxi, 28 Jinnan, 32 Qinchuan and 26 Limousin × Luxi cattle) were used to estimate allele frequencies and gene substitution effects on several beef carcass traits.

The frequency of three mitochondriai point mutations,1555A→G,3243A→G,7445A→G,was examined using restriction fragment length polymorphism annlysis in 262 Chinese patients with NSHL,con- sisting of 168 sporadic cases,69 sib pairs,and 25 families with affected subjects in more than one generation.

方法收集非综合征型神经性耳聋病例262例，其中散发病例168例，69例同代有耳聋患者，25例不止1代有耳聋患者，采用限制性片段长度多态性分析线粒体基因中的下列3个点突变：1555A→G，3243A→G，7445A→G。

Among them multi-types of body colour and special types of hosts are the most universal phenomena. In our experiment, methods of microsatellite primer PCR molecular marker and partial gene sequence analysis of mitochondrial DNA COⅠ-Ⅱwere used to analyze genetic diversity of two body colour bio-types (red bio-type and green bio-type) of green peach aphid from different plants and relationship between green peach aphid and host plants by separately selecting individuals of aphid from rape, Chinese cabbage and tobacco. The main results as follows: 1. Selecting An Ruisheng'method of extracting DNA from small sized insect, using this method can extract DNA well and steadily.
