Summary An equation is given for the estimation of selective values from data obtained by mark‐recapture experiments, assuming that selective pressures remain constant while the experiments are carried out. The equation does not have an explicit solution but can readily be solved using a trial‐and‐error method. The use of the equation is illustrated on some data reported by Kettlewell et al. (1969) from an experiment involving typica and edda morphs of the moth Amathes glareosa . It is found that the edda morph apparently had a selective advantage of about 12% per day compared to the typica morph and that this is significantly different from zero. Using another method Kettlewell concluded that the selective advantage of the edda morph was only 7% and that this was not statistically significant.
