On the estimation of effective number of alleles from electrophoretic data.
Estimation of the effective number of alleles in natural populations from the frequencies of electrophoretically detected alleles involves significant ambiguity, which should be explicitly considered in the estimate. For large genetic populations the ambiguity importantly affects the value of n(e).

Analysis of enzyme variation in natural populations of the butterfly Colias eurytheme.
The use of internal standards in the separation of proteins by gel electrophoresis is shown to offer significant advantages over other control procedures heretofore used in electrophoretic surveys of enzyme variation in natural populations. By the use of such internal standards, a previously undetected class of micro-variability among the enzymes of wild insects has been demonstrated.
