A refSNP report shows 90 individuals were sampled for genotype data. Is 90 the total number of individuals contributing chromosomes for the assay sample size and the population data sample size?
90 is the total number of individuals contributing to individual genotype data. Please note that this number is independent of the assay sample size and the population data sample size since the person(s) who submitted the genotype data may not be the same person who submitted the original assay. In theory, it is possible that the same individuals were used in the discovery assay and for the genotype data, but dbSNP does not always have information with regard to this.
