The characteristics of quantitative traits; Multiple-factor hypothesis for quantitative inheritance; Calculating the number of genes;additive allele;nonadditive allele.

问题与应用：明确质量性状与数量性状的特点，为什么二者之间既有着明显的区别，又无截然分开的绝对界限？

IGF2, which encodes a protein functioning as a fetal growth factor and a cell mitogen, is expressed only from paternally allele in most tissues but from both alleles in adult liver. H1 9, which acts as an RNA, is a gene of unknown function and expressed only from maternally allele.

IGF2编码的胰岛素样生长因子-2是一种胚胎生长因子及细胞有丝分裂原，在人体内大多数组织中特异地表达父系来源的等位基因，而母源等位基因处于印记状态。H19表达一种功能尚不清楚的RNA，其印记状态与IGF2相反，目前发现H19在正常组织内均为母源等位基因表达，父源等位基因印记。

Kdr resistance and determination of frequences of kdr gene in house fly field population L1014F is the most common amino acid substitution in the kdr allele. The frequency of the L1014F kdr allele was determined by the method of PASA in fourteen field populations of houseflies with resistance factors at LD〓 for pyrethrin/ piperonyl butoxide and bioresmethrin/piperonyl butoxide from 4 to 29 and 2 to 98, respectively.

击倒抗性及kdr基因频率在家蝇野生种群中的检测 L1014F是击倒抗性等位基因最常见的突变位点。14个家蝇种群对除虫菊酯／胡椒基丁醚和苄呋菊酯／胡椒基丁醚的LD〓抗性倍数分别为4到29和2至98。

Thus when random fluctuations result in a deviation of the allele frequency between the parent and offspring generations, that deviation establishes new expected values for the allele distributions in the next generation to follow.

因此，当随机波动导致父母和子代之间产生等位基因频率出现偏差，这种偏差为紧接着的下一代的等位基因分布建立了新的预期值。

H6 heliotype did not found in Nanyang cattle and Luxi cattle. 5 Yellow cattle and yak had different allele in UMN0307 locus, so this locus could be used to differentiate yellow cattle and yak. We did not find yak's allele in yellow cattle populations, which indicated that there was not yak male origin in these 4 populations.

UMN0307 位点在牦牛和普通牛、瘤牛有不同的等位基因，可以用于牦牛和瘤牛、普通牛的分离鉴定；在本实验研究个体中，没有在黄牛中发现和牦牛相同的等位基因，表明至少在这四个群体所检测个体中，没有发现牦牛的父系起源。

Results It was able to analyze the DNA polymorphism using 15 polymorphic microsatellite loci between Macaca mulatta and Macaca irus. The allele numbers were more than 7, and there were differences in 11 allele numbers between the two groups.

结果 筛选的15个具有显著多态性的微卫星DNA位点对恒河猴和食蟹猴种群可以进行DNA多态性分析，其等位基因数目均在7个以上，且两群体间有11个位点的等位基因数存在一定的差异。

A mispairing PCR-RFLP technique was applied in this study to determine the Insulin-like Growth Factor 2(IGF2) gene intron3 G3072A mutation in an outbred Landrace and Large White, and the gelded boars from Landrace×Large White cross. The difference of corresponding traits and the genetic effects of the boars inherited from parental A allele and inherited from parental G allele were analyzed.

采用错配PCR-RFLP技术鉴别了长白猪和大白猪纯种以及长白×大白猪杂交后代去势公猪胰岛素样生长因子2(IGF2)基因内含子3的3072位点变异，分析了遗传来自父本不同等位基因个体间的相关性状差异及不同等位基因的遗传效应。

32B is a key Chinese maintainer line used for hybrid rice breeding. However, it isof poor quality because of a high AAC, a high gelatinization temperature, andnon-fragrant. It is known that the AAC, GT and fragrance traits are controlled by the Wx,starch synthaseⅡa and fragrance genes. The quality ofⅡ-32B was improved byintrogressing the Wx, SSⅡa and fgr genes from YixiangB, another maintainer line, that has alow AAC, a low GT and fragrant sensory, with the assistance of the functional markers. TheWx microsatellite [_(17) allele] SSⅡa single nucleotide polymorphism and fgrinsertion/deletion allele (8 bp), were transferred toⅡ-32B by two backcrosses and twoselfings.

通过两次回交和两次自交，并利用功能标记的辅助选择，将来自品质优良保持系宜香B(有香味，低AAC、GT)中Wx-_(17)、SSⅡa-TT和fgr(8bp缺失)等位基因导入到品质较差Ⅱ-32B(高AAC，高GT，没有香味)中，以改良其品质。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.
