I have no expertise in biology, I'm a data scientist, and I would like to know if it makes sense, from the biological point of view, to analyze data (SNP data) coming from a single chromosome, and not all 22 chromosomes, to predict the risk of a certain disease.
Should I obligatorily use data from all chromosomes? Why?
Thank you very much. And sorry if it is a very basic question, but I really would like to understand this.
