Although combining population genomic and association approaches is a powerful way to overcome some of the limitations of associations studies, GWAS in populations where phenotype is associated with strong population structure produces problems in separating true positives from loci that diverged simply as a function of demographic processes (see File S5).
The main limitation of association studies is the observational nature of the existing evidence.
The main limitation of association analyses is the requirement for sufficient markers to provide a high chance of identifying markers in LD with all important QTN.
Nevertheless, the haplotype cluster-based analysis can have the more limitation of association analysis compared with diplotype-based analysis as if allele-based analysis can have less diversity than genotype-based analysis.
This phenomenon results from two limitations of genotype association: the genotyping model in the association test is limited to three genotypes (AA, BB, AB) and the genotyping quality is dependent on the sample-wide intensity mapping of the A and B alleles.
Because of these limitations, direction of association cannot be inferred.
Still, association does not mean causation, which is a limitation of association-based studies.
In addition, it includes 'users' of such studies who wish to understand the basic premise, design, and limitations of genetic association studies to interpret the results.

Due to some limitations of the association of Chado, GBrowse, Apollo and Artemis, annotation communities have been compelled to set up multiple Chado databases.
