Andy Chen - By using GWAS (Genome-Wide Association Studies), he found specific genetic markers (pieces of DNA) that are linked to traits that make the wheat more resistant to cold temperatures ( winter hardiness ). These findings could help improve the ability of winter wheat to survive in colder conditions. 1. What is GWAS? Scientists use GWAS to scan the entire genotype (DNA) of many individuals to identify which genetic variations are linked to specific phenotypes (traits or diseases). For example, they might look for genetic markers that explain why a plant has a certain height or why a person is more resistant to a disease. 2. What is linkage analysis? Linkage analysis is a method used to find the location of genes on chromosomes that are responsible for specific traits or diseases. It’s based on the idea that genes that are physically close to each other on a chromosome tend to be inherited together. Linkage analysis helps scientists figure out which genes are passed down fr
