What is a genomewide scan?

A genomewide scan is a research method used to identify associations between genetic variants and traits or diseases across the entire genome. It typically involves analyzing single nucleotide polymorphisms (SNPs) in large populations to detect regions of the genome that may contribute to specific phenotypes. This approach helps researchers pinpoint potential genetic factors involved in complex diseases and can aid in understanding the genetic basis of various traits. Genomewide scans are often employed in studies of heritable conditions, including common diseases like Diabetes and Heart disease.
