✻ `PCR-RFLPs` are data curated in the early days of the QTLdb development and retrospectively categorized. `N/A` are those data that were based on calculate linkage map locations without any marker information on the locations.
NOTE: On this site, the term "QTL" may have collectively included quantitative loci, SNP associations, and eQTL data.
