    Brief Exchanges on Selection of Genomic Regions and Genes Related to Adaptation and Fertility Traits of Two Colombian Creole Cattle Breeds
    Author(s): C. De Leon* and R. Martinez

    Natural selection and domestication in livestock species are one of the main evolutive changes resulting in phenotypic adaptations; these patterns create genetic signatures within the genome. To discovery signatures and genes involved in adaptation and fertility traits in two Colombian creole cattle breeds Blanco orejinegro (BON) and Sanmartinero (SM) in the present study it was detected selected genomic regions by comparing differences in regional linkage disequilibrium (LD) using 58,868 single nucleotide polymorphisms (SNPs) from BON and 57482 SNPs from SM. Also was estimated the variation of genome-wide LD between populations using the VARLD program. The top 0.1 and 0.01th percentiles of standardized VarLD scores were used as a criterion for all comparisons. Ten regions were detected on chromosomes 3, 5, 11, 15, 18, 21, 22, 23, 25 and 29 and gene.. View more»
