Question

Quizplus · Accepted Answer

GWAS is a type of forward genetic screen that involves scanning a large number of genetic variants across the genome to identify associations between genetic variations and particular traits or diseases. It is not a twin or adoption study, which involve comparing the similarity of traits between genetically related individuals (such as twins or adopted siblings) or genetically unrelated individuals (such as adoptive parents and children). It is also not a reverse genetic screen, which involves manipulating or disrupting genes to observe their effects on a particular trait or phenotype.
