Introduction to GWAS
Climate change significantly impacts livestock, with heat stress being a primary concern. Traditional breeding methods are insufficient for developing climate-resilient animals. GWAS, utilizing single-nucleotide polymorphisms (SNPs), provides a powerful tool to identify genetic variations linked to complex traits like thermo-tolerance, reproduction, and disease resistance. Integrating GWAS with AI and ML can enhance prediction accuracy and efficiency in breeding programs, ensuring sustainable livestock production and global food security.

Genetic Models for Climate Resilience
Various genetic models are employed to establish climate resilience. Genomic selection models like GBLUP and ssGBLUP predict breeding values, while GWAS-based statistical models identify SNPs and genomic regions for adaptive traits. Models such as GLMM, MLM, and Bayesian approaches account for population structure and relatedness, enhancing the reliability of SNP identification. Advanced models like FarmCPU improve power and reduce false positives, critical for complex trait analysis in livestock.

GWAS for Important Functional Traits
GWAS is a valuable tool for mapping QTLs associated with critical functional traits in livestock, including production, reproduction, immune response, adaptation, and low methane emission. By identifying SNPs and candidate genes, GWAS helps unravel molecular mechanisms underlying these traits, enabling targeted breeding. Examples include genes for milk yield (TLR4, GRM8), heat tolerance (HSF1, TXNRD2), and methane emission (TRPS1, CYP51A1), all crucial for developing climate-resilient breeds.
Case Study: Milk Yield & Heat Stress
"GWAS identified six SNPs for total milk yield within TLR4, GRM8, and SMAD3 genes, indicating their involvement in energy utilization and metabolic regulation under heat stress."
