Abstract
The population genetic structure of Arabidopsis thaliana was investigated in and among 16 British populations by means of an electrophoretic survey of nine enzyme systems. Seven out of 17 allozyme loci examined were polymorphic. One polymorphic locus was used as a marker locus for estimating outcrossing rates. No outcrossing was observed within any of seven populations surveyed and a joint estimate of the upper limit of outcrossing, t̂u, indicated that average outcrossing in the wild does not exceed 0·3 per cent. The genetic structure of A. thaliana as measured by Nei's gene diversity statistics, gene correlation F statistics, and estimates of multilocus genotypic diversity is concordant with that which is expected for a plant species which shows almost complete uniparental reproduction. Despite considerable genetic differentiation between populations, there was no evidence of a division between English and Scottish populations based on genetic distance.
