The 1000 genomes research article(http://www.nature.com/nature/journal...ture11632.html) studies f2 variants. They refer to these as "Variants present twice across the entire sample (referred to as f2 variants), typically the most recent of informative mutations, are found within the same population in 53% of cases". Can anybody please elaborate/explain as to what are these f2 variants? I am confused as to are these variants - ones with the variant allele is present on both the chromosomes at the same locus(Homozygous alternate) or something else.

Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...10-14-2026, 09:55 AM
