A chromosome-wide QTL mapping on chromosome 2 to identify loci affecting live weight and carcass traits in F2 population of Japanese quail
DNA markers growth traits QTLs
2016/7/6
The Japanese quail (Coturnix japonica) is a considerable species which is often used for animal modelling in breeding researches. This study aims to detect quantitative trait loci (QTL) underlying gro...
Characterization of QTL for Growth and Meat Quality in Combined Pig QTL Populations
QTL Joint Data Meat Quality Korean Native Pig Landrace Yorkshire
2016/5/9
This study was conducted to detect quantitative trait loci (QTL) for thirteen growth and meat quality traits in pigs by combing QTL experimental populations. Two F2 reference populations that were sir...
QTL Scan for Meat Quality Traits Using High-density SNP Chip Analysis in Cross between Korean Native Pig and Yorkshire
Illumina Porcine 60K SNP Beadchip QTL Meat Quality Korean Native Pig Yorkshire Pig
2016/5/6
We attempted to generate a linkage map using Illumina Porcine 60K SNP Beadchip genotypes of the F2 offspring from Korean native pig (KNP) crossed with Yorkshire (YS) pig, and to identify quantitative ...
Application of Linkage Disequilibrium Mapping Methods to Detect QTL for Carcass Quality on Chromosome 6 Using a High Density SNP Map in Hanwoo
QTL Linkage Disequilibrium Carcass Traits Hanwoo SNP
2016/5/6
The purpose of this study was to detect QTL for carcass quality on bovine chromosome (BTA) 6 using a high density SNP map in a Hanwoo population. The data set comprised 45 sires and their 427 Hanwoo s...
QTL Identification Using Combined Linkage and Linkage Disequilibrium Mapping for Milk Production Traits on BTA6 in Chinese Holstein Population
Fine Mapping QTL Bos Taurus autosome 6 Milk Production Traits

Milk production traits are important economic traits for dairy cattle. The aim of the present study was to refine the position of previously detected quantitative trait loci (QTL) on bovine chromosome...
控制近交和世代离散情况下多性状、多QTL的最优化选择
QTL 最优化 近交
2009/9/8
在世代离散的情形下，应用计算机随机模拟技术研究当候选个体的遗传贡献和施加给QTL的相对权重一起被最优化时，使用多性状、多QTL信息的QTL优化选择所能获得的潜在的额外遗传优势。用一个实际育种猪群的参数进行模拟，选择是直接针对窝产活仔数和达100 kg日龄进行，每个性状都有2个不同效应大小的QTL正在和相应的多基因一起分离。将优化QTL选择与标准QTL选择和常规BLUP选择进行比较发现，综合了遗传贡...
