The results indicate that white feather of White Leghorn chicken and black feather of Shou-Guang chicken are complete dominance heredity to hemp feather of Tibetan chicken. Hemp feather is determinate by two or more than two alleles. Only these two or above two alleles is of concurrence, then hemp feather displays possibly. Id/id allele decided shank color is of sex-linkage inheritance, recessive gene id homozygote has process which expresses gradually. We confirm that genotype of shank color in White Leghorn chicken in this paper is the dominant homozygote.
结果表明，白来航鸡的白羽和寿光鸡的黑羽对藏鸡麻羽的遗传方式是完全显性遗传；麻羽是由两个或两个以上的等位基因决定的，只有同时存在这两个或两个以上的等位基因，才可能表现出麻羽来；决定胫色性状的Id/id基因为伴性遗传，隐性基因id在纯合子时有个逐步表达的过程；本研究证实了所用白来航公鸡胫色性状的基因型为显性纯合子。

Result: Contrary to European and American people, I allele frequency of Han nationality is higher than that of D allele (P.05); II genotype frequency and DD genotype frequency are noticeably different from that of European and American people (P.01); No DD genotype appear in the excellent athletes, which is noticeably lower than that of control group and athlete group (P.05) and that of the excellent athletes reported in other countries; the frequency distribution of II genotype in Marathon is noticeably higher than that in 5km distance running(P.10); The changing of I allele Jl genotype IP ID genotype frequency indicates a stronger unary liner relation (r=0.9985) with the running distance lengthening(5ktru lOkrru Marathon).
结果显示：与欧美人群相反，汉族I等位基因频率高于D等位基因（P＜0.05）；汉族II型纯合子频率和DD型纯合子频率非常显著地区别于欧美人群（P＜0.01）；在优秀运动员中，DD型纯合子未出现一例，显著低于对照组和运动员（P＜0.05），也显著低于国外已报道的优秀运动员；马拉松项目II型频率分布显著高于5km（P＜0.10）；I等位基因、II基因型和ID基因型的频率变化伴随专项距离（5km、10km、马拉松）的增加呈现强相关的一元线性关系（r=0.9985）。

Among 13 DRB1 alleles detected in Drung ethnic, a unique feature of its allele distribution is having predominant homozygotes (64.9%) in all studied populations. In Drung HLA-DRB1〓14011 is highly prevalently presented with the allelic frequency of 70.07%.
独龙族中检出13种等位基因，其遗传学显著特点是纯合子类型检出较多，纯合子36个，占被检样品的64.9％，DRB1*14011分布占绝对优势，占被检出等位基因的70.07％。

Results The vaccinal vestige, BCO immunization and familial traits were the risk factors of tuberculosis. Frequency of wildness, mutant heterozygote and homozygote of MBP-54 was difference in cases and controls.
MBP-54位点野生型、突变型杂合子、突变型纯合子3种基因型在病例组和对照组中的分布频率不同。

The functional allele at the W locus is Ipmyb2, which was newly found in Chinese populations, and it differs mainly in the intron regions from those of the reported allele Ipmyb1; in comparison to Ipmyb2, the newly found second allele ipmyb2 has eight substitutions in the exons, a 6-bp deletion, and a 19-bp deletion, causing ORF shifting, and exists mostly in white-flowered individuals.
以上结果表明：1花青素代谢途径上酶基因的位点均有一定程度的多态，其中尤以ANS为最高；调控基因ipmyb2的核苷酸缺失造成该基因停止功能，使其纯合子的个体开白色花。2授粉者所介导的花色表型选择确实在中国种群中发生，有可能进一步增加花色代谢途径上基因位点的遗传变异。

heterozygote：杂合子
贝特森还创用了纯合子(homozygote)、杂合子(heterozygote). 一个或几个座位上的等位基因相同的二倍体或多倍体称纯合子,不同时称杂合子. "基因"(Gene)这个名词是由丹麦的科学家约翰逊Johannsen于1909年提出的,取代了孟德尔的遗传因子.

homozygote：纯合子
而一对基因相同(aa或aa)者,称为纯合子(homozygote). 因为a对a是显性的,基因a的作用在杂合子时表现出来,所以短指症的遗传方式是常染色体显性遗传. 短指症的基因型有两种,纯合子(aa)和杂合子(aa),它们在临床表现上无区别,故为完全显性.
-
intercross：互交
再用杂合子小鼠互交(intercross),从出生的子代鼠中可鉴定、筛选出纯合子的基因打靶小鼠. 再经繁育可建立转基因小鼠品系.
