Abstract

We describe developments of regression-based methods for estimating the relationship between gene flow and distance using allelic variation at markerloci. These new methods allow the correct testing of the difference between regression slopes, and the assignment of confidence intervals to estimates from the regression equation, when the regression is between matrices of pairwise data, rather than between independent values. We show that there are significant differences in gene flow estimates from RFLPs and isozymes in sea beet. Estimates of the distance at which populations exchange one migrant per generation are lower for wild cabbage than for sea beet.
