Identifying Molecular Signatures from Sex Chromosomes: A Case for Indigenous Chicken Based on the Analyses of the Z Chromosome
Domestications and selection have led to phenotypic variation in chicken and has left traceable signatures within their genome. Indigenous chicken has been shaped more by natural selection [1] imposed by the environmental conditions, parasites, diets and diseases. Several candidate genes that contribute to adaptation to harsh scavenging tropical conditions, for instance, those linked to respons...
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 کاملWhole-genome scan for signatures of recent selection reveals loci associated with important traits in White Leghorn chickens.
Chicken is considered to be an excellent model for genetic studies of phenotypic and genomic evolution, with large effective population size, specialized commercial lines, and strong human-driven selection. High-density chicken SNP chips can help to achieve a better understanding of the selection mechanisms in artificially selected populations. We performed the genome-wide tests for the selecti...
متن کاملDetection of avian leukosis virus (ALV) in albumen of Shiraz commercial and local layer flocks using ELISA and RT-PCR
Avian leukosis viruses (ALVS) cause different types of tumours in poultry and can affect the health and egg production of the birds. To investigate the presence of the virus in chicken layer flocks in Shiraz, 222 egg albumen from local layer breeder (25 eggs), local layer grand parent (30 eggs), broiler breeder (60 eggs), commercial layer (46 eggs) and broiler grand parent (61 eggs) were tested...
متن کاملDetection and Molecular Characterization of Chicken Astrovirus from Broiler Flocks in Iran: The First Report
Background and Aims: Enteric diseases have had detrimental impacts on commercial poultry through depressing growth rates and caused considerable economic losses to poultry producers. Chicken astrovirus (CAstV) is one of the most common viruses related to enteric diseases in chickens, especially in young chicks. Materials and Methods: Chicken astroviruses were detected by reverse transcriptase ...
