WebComputing heterozygosity and the inbreeding coefficient (F) for each individual can quickly highlight outlier individuals that are e.g. inbred (strongly negative F), suffer from high sequencing error problems or contamination with DNA from another individual leading to inflated heterozygosity (high F),

The measures FIS, FST, and FIT are related to the amounts of heterozygosity at various levels of population structure. Together, they are called F-statistics, and are derived from F, the inbreeding coefficient.
