Y染色体分子遗传多样性是追溯动物起源、驯化历史和迁徙路线的重要工具,也可以用来反映动物的父系遗传多样性及用于研究群体间父系介导的杂交情况。Y染色体单倍型多样性可以分别通过Y染色体单核苷酸多态性(Y-SNP)和Y染色体微卫星多态性(Y-STR)或这二者结合起来构建精确的Y染色体单倍型。黄牛有3种父系起源(普通牛Y1、Y2和瘤牛Y3单倍型组),可以通过Y-SNP来区分,通过-STR标记可以区分Y1、Y2和Y3所具有的丰富的精细单倍型。本文汇集了包括中国在内的国内外黄牛Y染色体遗传多样性与起源进化的研究进展。 相似文献

Up to 173 African sires belonging to 11 different subpopulations representative of four cattle groups were analysed for six Y‐specific microsatellite loci and a mitochondrial DNA fragment. Differences in Y‐chromosome and mtDNA haplotype structuring were assessed. In addition, the effect of such structuring on contributions to total genetic diversity was assessed. Thirty‐five Y‐chromosome and 71 mtDNA haplotypes were identified. Most Y‐chromosomes analysed (73.4%) were of zebu origin (11 haplotypes). Twenty‐two Y‐haplotypes (44 samples) belonged to the African taurine subfamily Y2a. All mtDNA haplotypes belonged to the “African” taurine T1 haplogroup with 16 samples and nine haplotypes belonging to a recently identified subhaplogroup (T1e). Median‐joining networks showed that Y‐chromosome phylogenies were highly reticulated with clear separation between zebu and taurine clusters. Mitochondrial haplotypes showed a clear star‐like shape with small number of mutations separating haplotypes. Mitochondrial‐based FST‐statistics computed between cattle groups tended to be statistically non‐significant (p > .05). Most FST values computed among groups and subpopulations using Y‐chromosome markers were statistically significant. AMOVA confirmed that divergence between cattle groups was only significant for Y‐chromosome markers (ΦCT = 0.209). At the mitochondrial level, African sires resembled an undifferentiated population with individuals explaining 94.3% of the total variance. Whatever the markers considered, the highest contributions to total Nei's gene diversity and allelic richness were found in West African cattle. Genetic structuring had no effect on patterns of contributions to diversity. 相似文献

Both Bos indicus (zebu) and Bos javanicus (banteng) contribute to the Indonesian indigenous livestock, which is supposedly of a mixed species origin, not by direct breeding but by secondary cross-breeding. Here, the analysis of mitochondrial, Y-chromosomal and microsatellite DNA showed banteng introgression of 10-16% in Indonesian zebu breeds with East-Javanese Madura and Galekan cattle having higher levels of autosomal banteng introgression (20-30%) and combine a zebu paternal lineage with a predominant (Madura) or even complete (Galekan) maternal banteng origin. Two Madura bulls carried taurine Y-chromosomal haplotypes, presumably of French Limousin origin. There was no evidence for zebu introgression in five populations of the Bali cattle, a domestic form of the banteng. 相似文献

为了研究中国黄牛Y染色体SNPs的遗传多样性及父系起源,本研究利用PCR-SSCP与测序方法,选择4个牛Y-SNPs位点DDX3Y-7、UTY-19、ZFY-9和ZFY-10,分析了16个中国地方黄牛品种284头公牛与缅甸黄牛4头公牛Y染色体的遗传多样性.结果表明,在中国16个黄牛品种中,仅发现普通牛Y2和瘤牛Y3单倍型,表明只有Y2和Y3两种父系起源,尚未发现中国黄牛存在普通牛Y1单倍型的分子证据.4头缅甸黄牛均为Y3单倍型.在中国16个黄牛品种中,Y2和Y3单倍型频率分别为57.0％和43.0％,其中Y2单倍型频率在北方黄牛中占优势(98.3％),Y3单倍型频率在南方黄牛中占优势(76.1％),中原黄牛中普通牛Y2的单倍型频率较高,为63.8％0,瘤牛Y3的单倍型频率为36.2％.本研究证明,中国黄牛存在普通牛Y2和瘤牛Y3单倍型两种父系起源,Y2单倍型频率自北向南逐渐减少,Y3单倍型频率自北向南逐渐增加,中原地区为普通牛Y2和瘤牛Y3单倍型的交汇处. 相似文献

Kazakhstan is the largest landlocked country and contains two important propagation routes for livestock from the Fertile Crescent to Asia. Therefore, genetic information about Kazakhstani cattle can be important for understanding the propagation history and the genetic admixture in Central Asian cattle. In the present study, we analyzed the complete mtDNA D‐loop sequence and SRY gene polymorphism in 122 Kazakhstani native cattle. The D‐loop sequences revealed 79 mitochondrial haplotypes, with the major haplogroups T and I. The Bos taurus subhaplogroups consisted of T (3.3%), T1 (2.5%), T2 (2.5%), and T4 (0.8%) in addition to the predominant subhaplogroup T3 (86.9%), and the Bos indicus subhaplogroup of I1 (4.1%). Subsequently, we investigated the paternal lineages of Bos taurus and Bos indicus, however, all Kazakhstani cattle were shown to have Y chromosome of Bos taurus origin. While highly divergent mtDNA subhaplogroups in Kazakhstani cattle could be due to the geographical proximity of Kazakhstan with the domestication center of the Fertile Crescent, the absence of Bos indicus Y chromosomes could be explained by a decoupling of the introgression dynamics of maternal and paternal lineages. This genetic information would contribute to understanding the genetic diversity and propagation history of cattle in Central Asia. 相似文献

To assess the paternal gene pool in the Lidia bovine breed (or fighting bull), a total of 603 animals belonging to 81 herds classified in 33 lineages were genotyped for six Y chromosome microsatellites, one single nucleotide polymorphism and one indel. A total of 10 haplotypes were determined with a high level of frequency variation between them, ranging from 0.2 to 74%. All the haplotypes identified belong to two previously defined major haplogroups (Y1 and Y2). Two major paternal influences were identified, corresponding to the two most common haplotypes (H1Y1 and H3Y2) with frequencies of 74 and 18%, respectively. The detection of the INRA189-104 allele evidenced an African influence in the Lidia bovine breed. Low levels of haplotype diversity have been achieved and only eight lineages showed more than one haplotype. Analysis of molecular variance showed a high level of interlineage variance (F(ST) = 86%). Network results evidenced two main clusters made for those haplotypes belonging to Y1 and Y2 haplogroups, respectively. The findings support a high level of genetic structure together with a low level of genetic diversity in the Lidia bovine breed. 相似文献
