We have performed our analysis on the most common HLA-DRB1 alleles. HLA-DRB1 allele frequencies were obtained from the National Marrow Donor Program (NMDP). What is the purpose of analyzing the HLA-DRB1 alleles?
1) To determine the genetic diversity of the population
2) To identify potential matches for bone marrow transplantation
3) To study the association between HLA-DRB1 alleles and diseases
4) To investigate the evolutionary history of HLA-DRB1 alleles
