Extent and consistency across generations of linkage disequilibrium in commercial layer chicken breeding populations.
Recent studies report a surprisingly high degree of marker-to-marker linkage disequilibrium (LD) in ruminant livestock populations. This has important implications for QTL mapping and marker-assisted selection. This study evaluated LD between microsatellite markers in a number of breeding populations of layer chickens using the standardized chi-square (chi(2')) measure. The results show appreci...
متن کاملThe Extent and Distribution of Linkage Disequilibrium in Extensively Raised Chicken Populations of Southern Africa
The amount of linkage disequilibrium (LD) is an important source of information about historical events of recombination and allows inferences about genetic diversity and genomic regions that have undergone selection. Linkage disequilibrium is equally important in studying effective population size and rate of inbreeding particularly in extensively raised and wild animal populations where pedig...
متن کاملGenome Scan for Selection in Structured Layer Chicken Populations Exploiting Linkage Disequilibrium Information
An increasing interest is being placed in the detection of genes, or genomic regions, that have been targeted by selection because identifying signatures of selection can lead to a better understanding of genotype-phenotype relationships. A common strategy for the detection of selection signatures is to compare samples from distinct populations and to search for genomic regions with outstanding...
متن کاملLinkage disequilibrium in subdivided populations.
The linkage disequilibrium in a subdivided populaton is shown to be equal to the sum of the average linkage disequilibrium for all subpopulations and the covariance between gene frequencies of the loci concerned. Thus, in a subdivided population the linkage disequilibrium may not be 0 even if the linkage disequilibrium in each subpopulation is 0. If a population is divided into two subpopulatio...
متن کاملLinkage disequilibrium in human populations.
Whereas the human linkage map appears on limited evidence to be constant over populations, maps of linkage disequilibrium (LD) vary among populations that differ in gene history. The greatest difference is between populations of sub-Saharan origin and populations remotely derived from Africa after a major bottleneck that reduced their heterozygosity and altered their Malecot parameters, increas...
