What is the main purpose of genome-wide association studies (GWAS)? How can information from GWAS be used to inform scientists and physicians about genetic diseases?

Hello everyone and welcome to today's video. So how can the genome Wide Association study provide a comprehensive understanding of human genetic diseases. Well, the first question that we need to ask ourself in order to solve this problem is what is this genome wide association going to be providing what it is an association study? So it is going to be comparing one thing to another. In this case, it is going to be comparing the genome of individuals are affected by a disease to the genome of an individual that is not by doing. So we can understand how this genetic disease is going to work in terms of affecting the genome. Now knowing this, let's go over each of our answer choices so that we may solve this problem beginning by answer choice B model organisms are used to understand gene mutations impact on humans while there is no model organisms being used. We're just comparing or associating two genomes of two humans. So we're going to cancel this out. Then we have seen utilized for login to detect the evolution of strength or evolution is not going to be tested at all here. So we're going to also cancel this out. Then we have studied the presence of millions in the environment. Again, millions are now present in the study. So we're going to cancel this out. And this all leaves us with answer choice, the genomes of disease affected individuals or compare to the genomes of individuals that are not affected. And this can help shed light to these genetic diseases and how they affect the genome. So answer choice A is going to be the correct answer to our question. I really hope this helped you and I hope to see you on the next video.
