WebMar 1, 1998 · WRIGHT's fixation indices, or F-statistics, are the parameters most widely used to describe population structure. Wright (1969, pp. 294–295; 1978, pp. 80–89; and refs. therein) defined the fixation indices as correlations between uniting gametes.His treatment is restricted to neutral diallelic loci; it is somewhat artificial (because numerical … WebDec 12, 2014 · This leads to Wright's result that it is the number of migrants (Nm) rather than the migration rate (m) that determines Fst, and the same number of migrants will …

Wright originally developed his F-statistics as inbreeding coefficients, defined as a cor-relation between uniting gametes. This was long before the advent of allozymes and other molecular genetic markers, and Wright therefore assumed loci to be biall-elic.
