Unraveling genomic variants and selective sweeps in livestock: A comprehensive analysis and methodological overview

Abstract

This article delves into the exploration of genomic variants and selective sweeps in livestock, leveraging advanced technologies and bioinformatics tools to deepen our understanding. Through the utilization of next-generation sequencing (NGS), the identification of single nucleotide polymorphisms (SNPs) and insertions/deletions (Indels) is elucidated, underscoring their pivotal role in genetic analyses and breeding programs. Particularly, the spotlight is on whole-genome sequencing in goats, accompanied by an exhaustive overview of bioinformatics tools, accentuating their indispensable contribution to such endeavors. Moving forward, the discussion shifts to the profound impact of animal domestication on genetic diversity, shedding light on the detection of selection signatures and the classification of selective sweeps. This segment of the article highlights the various methodologies employed to identify selection signatures, ranging from population genetics approaches to landscape genomics analyses. By employing these diverse approaches, a nuanced understanding of livestock genetics and the intricate dynamics of selection for breeding and conservation purposes is achieved, providing valuable insights for future research and practical applications in livestock management.
