Reliability of genomic selection (GS) models was tested in an admixed population of Atlantic salmon, originating from crossing of several wild subpopulations. The GS models included ordinary genomic BLUP models (IBS-GS), using varying marker densities (1 to 220K) and a genomic IBD model (IBD-GS) using genomic relationships estimated through linkage analysis of sparse markers (ignoring LD). The ...

Molecular markers and genetic maps are useful tools in genetic studies. Novel molecular markers and their applications have been developed in recent years. With the recent advancements in sequencing technology, the genomic sequences of an increasingly great number of fungi have become available. A novel type of molecular marker was developed to construct the first reported linkage map of the ed...

Terminal drought is a major constraint to chickpea productivity. Two component traits responsible for reduction in yield under drought stress include reduction in seeds size and root length/root density. QTL-seq approach, therefore, was used to identify candidate genomic regions for 100-seed weight (100SDW) and total dry root weight to total plant dry weight ratio (RTR) under rainfed conditions...

In this study, 37 transcriptome-derived simple sequence repeat (SSR) markers and 18 genomic SSR markers were developed and characterized in the Chinese perch, Siniperca kneri Garman. The average allele number per locus was 5.1 (range: 2-8) for transcriptome-derived SSRs and 3.8 (range: 2-5) for genomic SSRs. The average observed and expected heterozygosities were 0.666 (range: 0.000-1.000) and ...

Mental retardation (MR) is one of the most frequently found major genetic disorders around the world, affecting 1-3% of the people in the general population. The recent advancement in molecular biology and cytogenetic study has made possible the identification of new genes for a variety of genetic disorders including autosomal recessive MR. Recessive genetic disorders are common in Pakistan due...

The systematic analysis of polymorphisms across large parts of the human genome has begun to provide the first information on haplotypes and the problem of linkage disequilibrium across large genomic regions. These data suggest that significant regions of the genome show highly conserved haplotypes, potentially enhancing the ability to detect disease associations.

Single base pair differences between otherwise identical DNA molecules can result in altered melting behavior detectable by denaturing gradient gel electrophoresis. We have developed a simplified procedure for using denaturing gradient gel electrophoresis to detect base pair changes in genomic DNA. Genomic DNA is digested with restriction enzymes and hybridized in solution to labeled single-str...

Progress in molecular biology has opened the way to identifying genes involved in predisposition to multigene diseases. The two methods currently used for this purpose--analysis of candidate genes and systematic genomic screening--have given interesting but only very partial results. The problem is complicated by the large number of genes involved, their low penetrance, and linkage disequilibrium.

Extensive, new databases of single-nucleotide polymorphisms (SNPs) provide a powerful resource for disease gene discovery, and they will be even more useful as more frequency data become available. Interesting observed genomic patterns include SNP deserts (regions of low SNP incidence) and lengthy regions of linkage disequilibrium containing only a few haplotypes. A variety of genetic studies w...
