Natural And Artificial Selection Of Multiple Alleles Revealed Through Genomic Analyses, Jana Biová, Ivana Kaňovská, Yen On Chan, Manish Sridhar Immadi, Trupti Joshi, Kristin Bilyeu, Mária Škrabišová

Biomedical Sciences

Genome-to-phenome research in agriculture aims to improve crops through in silico predictions. Genome-wide association study (GWAS) is potent in identifying genomic loci that underlie important traits. As a statistical method, increasing the sample quantity, data quality, or diversity of the GWAS dataset positively impacts GWAS power. For more precise breeding, concrete candidate genes with exact functional variants must be discovered. Many post-GWAS methods have been developed to narrow down the associated genomic regions and, ideally, to predict candidate genes and causative mutations (CMs). Historical natural selection and breeding-related artificial selection both act to change the frequencies of different alleles of …
